An In Situ Automated System for Real-Time Monitoring of Failures in Large-Scale Field Emitter Arrays

Nano-scale vacuum transistors (NVCTs) based on field emission have the potential to operate at high frequencies and withstand harsh environments, such as radiation, high temperatures, and high power. However, they have demonstrated instability and failures over time. To achieve high currents from NVCTs, these devices are typically fabricated in large-scale arrays known as field emitter arrays (FEAs), which share a common gate, cathode, and anode. Consequently, the measured currents come from the entire array, providing limited information about the emission characteristics of individual tips. Arrays can exhibit nonuniform emission behavior across the emitting area. A phosphor screen can be used to monitor the emission pattern of the array. Additionally, visible damage can occur on the surface of the FEAs, potentially leading to the destruction of the gate and emitters, causing catastrophic failure of the FEAs. To monitor damage while operating the device, an ITO-coated glass anode, which is electrically conductive and visible-light-transparent, can be used. In this work, a method was developed to automatically monitor the emission pattern of the emitters and the changes in surface morphology while operating the devices and collecting electrical data, providing real-time information on the failure sequence of the FEAs.

RhCo alloyed nanodendrites as an efficient electrocatalyst for boosting electro oxidation of ethylene glycol in alkaline media

Since Pt- and Pd-based catalysts, as the most common anode catalysts, usually suffer from CO poisoning issue during the electro oxidation of ethylene glycol, it is essential to explore more high-efficiency Pt- and Pd-free ethylene glycol oxidation reaction (EGOR) catalysts for better service in direct ethylene glycol fuel cells (DEGFCs). In this work, RhCo alloyed nanodendritic catalysts applied on EGOR in alkaline solution are designed and synthesized by a solvothermal method. The RhCo nanodendrites consist of radially distributed pine tree shaped flakes and rod-like crystals. The mass activity for the as-prepared Rh3Co1 nanodendrites during the EGOR reaches up to 3018.7 mA mg−1, which is 2.2-folds higher than that of commercial Pt/C. Moreover, the Rh3Co1 nanodendrites exhibit better stability and CO tolerance toward the EGOR than pure Rh nanodendrites and commercial Pt/C. Experimental observations in combination with density functional theory (DFT) calculations reveal that the notably promoted catalytic performances of Rh3Co1 nanodendrites are mainly attributed to the distinct nanodendritic morphology and the synergistic effect of Rh and Co. This work provides a valuable insight for developing efficient electrocatalysts for DEGFCs.

A new approach for improving the quality of the carbon anode for aluminum electrolysis – An impregnation-baking process

Prebaked carbon anode is the primary consumable material in the aluminum reduction cell, and its quality directly affects the energy consumption of aluminum production. An impregnation-baking process of the anode was proposed to reduce the anode porosity, improve the quality of the anodes, and reduce additional carbon consumption. The theoretical analysis and industrial testing on the impregnation-baking process were carried out. Firstly, the coal tar pitch was immersed into the anode carbon block through the impregnation process. An anode impregnation model was developed and used for theoretical calculations to analyze the effects of pressure and temperature on the impregnation process. The accuracy of the model was verified experimentally. Secondly, the impregnated anodes were placed in an electromagnetic induction heating furnace for baking to carbonize the immersed pitch. The thermogravimetric and pyrolysis kinetics methods were used to analyze the baking process of the impregnated anodes. Finally, the impregnated-baked anodes were compared with common anodes regarding their impact on the technical and economic indicators of the aluminum electrolysis process in industrial tests. The results showed that the physicochemical properties of the impregnated-baked anodes were significantly improved, with the bulk density increase of 0.1 g/cm3, air permeability reduction of 0.54 nPm, compressive strength enhancement of 9.43 MPa, and electrical resistivity decrease of 10 uΩ·m. The anode service life was increased from 31 to 35 days, the current efficiency was increased by 0.44 %, and the operating voltage was reduced by 17 mV, which improved economic benefit significantly.

Flexible 2 × 2 multiple access visible light communication system based on an integrated parallel GaN/InGaN micro-photodetector array module

In recent studies, visible light communication (VLC) has been predicted to be a prospective technique in the future 6G communication systems. To suit the trend of exponentially growing connectivity, researchers have intensively studied techniques that enable multiple access (MA) in VLC systems, such as the MIMO system based on LED devices to support potential applications in the Internet of Things (IoT) or edge computing in the next-generation access network. However, their transmission rate is limited due to the intrinsic bandwidth of LED. Unfortunately, the majority of visible light laser communication (VLLC) research with beyond 10 Gb/s data rates concentrates on point-to-point links, or using discrete photodetector (PD) devices instead of an integrated array PD. In this paper, we demonstrated an integrated PD array device fabricated with a Si-substrated GaN/InGaN multiple-quantum-well (MQW) structure, which has a 4×4 array of 50 μm×50 μm micro-PD units with a common cathode and anode. This single-integrated array successfully provides access for two different transmitters simultaneously in the experiment, implementing a 2×2 MIMO-VLLC link at 405 nm. The highest data rate achieved is 13.2 Gb/s, and the corresponding net data rate (NDR) achieved is 12.27 Gb/s after deducing the FEC overhead, using 2.2 GHz bandwidth and superposed PAM signals. Furthermore, we assess the Huffman-coded coding scheme, which brings a fine-grain adjustment in access capacity and enhances the overall data throughput when the user signal power varies drastically due to distance, weather, or other challenges in the channel condition. As far as we know, this is the first demonstration of multiple visible light laser source access based on a single integrated GaN/InGaN receiver module.

Study on the mechanism of glass-SiC-glass anodic bonding process

The connection of silicon carbide (SiC) to glass is important for the development of microelectromechanical systems. In the study, glass-SiC-glass with SiC as common anode was effectively bonded by using anodic bonding technology in atmosphere. The interfacial microstructure of bonded joints was analyzed by using scanning electron microscope, energy-dispersive spectrometer and transmission electron microscope. The effect of the bonding voltages and bonding temperatures on the interfacial microstructure and mechanical property of glass/SiC/glass was investigated. The results indicated that a Na+ depletion layer formed in the glass adjacent to the SiC/glass interface due to the decomposition of Na2O compound in the glass and the migration of Na+ towards the upper surface of glass during anodic bonding. With elevating bonding temperatures or bonding voltages, the thickness of Na+ depletion layer was gradually increased and more O2− accumulated at the SiC/depletion layer interface, which was beneficial for the tensile strength of joints. But owing to the increased residual thermal stress, the tensile strength of the joints dropped with enhanced bonding temperature. The maximum tensile strength of the joint was about ∼12.8 MPa when bonding at 450 °C/1000 V/1 min. The joint mainly ruptured in the glass with a brittle fracture mode.

Structures, performances and applications of green biomass derived carbon in lithium-ion batteries

Most countries worldwide have committed to reaching carbon neutrality by the end of the century, with the aim to achieve Net Zero before 2060. To reduce the dependency of energy demands on fossil fuels, use of renewable energy and its gradual transition into the overall energy portfolio becomes increasingly critical. The solar and wind energy accounts for a major part of renewable energy. Considering unstable and noncontinuous production of electricity from these two sources, energy storage becomes essential. Lithium-ion batteries (LIBs) have become the most favorable choice of energy storage due to their good electrochemical performance (high capacity, low charge leakage and good cycle performance) and safety, in particular for portable (3C products, electric vehicles and drones) and stationary applications as well as for emergency electricity supply. However, the specific capacity of graphite, the most common commercial anode material, is reaching its theoretical limit, posing great challenges for improving the overall capacity of LIBs. It is therefore necessary to develop anode materials of higher capacity and better cycle performance. Biomass-derived carbon materials are ideal candidates for further enhancing the performance of LIBs due to their special microstructures, functional diversity and easy structure regulation. Most of these materials can reach capacities exceeding 500 mAh g-1, even the best for more than 1,000 mAh g-1 combined with other anode materials. This review provides an in-depth analysis of diverse carbon sources derived from biomass, categorized based on their distinct structural characteristics, with the focus on evaluating the current roles and bottlenecks of carbon as a component of the electrode materials used in LIBs. The failure mechanisms associated with biomass-derived carbon in LIBs are summarized, with potential solutions to these issues being proposed. The potential challenges and prospects for biomass-based LIBs are identified and thoroughly discussed. Overall, this review aims to serve as a resource for the strategic design and advancement of carbon-based materials, to achieve next-generation LIBs of superior performance.

Study on Influencing Parameters of Total Phosphorus Degradation in Cattle Farm Wastewater by Electrocoagulation Using Magnesium, Aluminum, and Iron Electrodes

Magnesium, aluminum, and iron electrode were common anodes in electrocoagulation (EC), but there were few studies comparing the influence of operating parameters on the reaction and the effects of these three different anodes in removing total phosphorus (TP) in cattle farm wastewater (CFW). This study used these three different electrodes as the anode of the electrocoagulation method. The operating parameters such as electrode distance (ED), initial pH, and voltage were examined by the Taguchi method and single-factor method. The result of Taguchi analysis shows that voltage has a significant impact on TP removal of magnesium (Mg) and aluminum anode (Al), and ED has a significant impact on TP removal of magnesium and iron anode (Fe). Among the three operating parameters, the first in the order of the impact on the reaction was ED because ED has the greatest influence on the dissolution of the anode. The result of single-factor analysis shows that the optimum conditions of Mg were ED = 3 cm, voltage = 5 V, pH = 7, Al were ED = 3 cm, voltage = 5 V, pH = 5, and Fe were ED = 3 cm, voltage = 5 V, and pH = 7. For Mg and Fe, the voltage and reaction results follow the second-order reaction kinetics, and Al is the first-order reaction kinetics. Through comparison of the three anodes, it was found that Al worked best in actual CFW. It was noted that the conditions obtained by the single-factor method were more economical in the treatment of actual CFW. This work could provide reference for determining the extent of the influence of operating parameters when other contaminants are removed, and provide reference for comparing the other anodes in EC.

Review and New Perspectives on Non-Layered Manganese Compounds as Electrode Material for Sodium-Ion Batteries.

After more than 30 years of delay compared to lithium-ion batteries, sodium analogs are now emerging in the market. This is a result of the concerns regarding sustainability and production costs of the former, as well as issues related to safety and toxicity. Electrode materials for the new sodium-ion batteries may contain available and sustainable elements such as sodium itself, as well as iron or manganese, while eliminating the common cobalt cathode compounds and copper anode current collectors for lithium-ion batteries. The multiple oxidation states, abundance, and availability of manganese favor its use, as it was shown early on for primary batteries. Regarding structural considerations, an extraordinarily successful group of cathode materials are layered oxides of sodium, and transition metals, with manganese being the major component. However, other technologies point towards Prussian blue analogs, NASICON-related phosphates, and fluorophosphates. The role of manganese in these structural families and other oxide or halide compounds has until now not been fully explored. In this direction, the present review paper deals with the different Mn-containing solids with a non-layered structure already evaluated. The study aims to systematize the current knowledge on this topic and highlight new possibilities for further study, such as the concept of entatic state applied to electrodes.

Integrating High-Sensitivity Photodetector and High-Energy Aqueous Battery in All-in-One Triple-Twisted Fiber.

Fiber-shaped photodetectors (FPDs) have attracted special attention to wearable health monitoring due to their 3D absorption capabilities. However, the practical application of traditional FPDs is severely limited by the irreversible degradation of performance caused by vulnerable interface compatibility on complex deformation and a single function. Here, an integrated photoelectrochemical FPD/battery device (FPDB) is designed, consisting of a common electrode, photoanode, anode, and sol-gel electrolyte as an isolation layer, which not only effectively avoids the short circuit problem of FPD but also endows high-efficiency energy storage capacity. As expected, the resulting all-in-one triple-twisted fiber-shaped FPDB simultaneously achieves high responsiveness of 151.45 mA W-1 and excellent volume capacity of 18.75 mAh cm-3. Such a stable architectural design and multifunctional integration of functional fibers accelerate the development of next-generation wearable fabrics.

Research progress of organic liquid electrolyte for sodium ion battery.

Electrochemical energy storage technology has attracted widespread attention due to its low cost and high energy efficiency in recent years. Among the electrochemical energy storage technologies, sodium ion batteries have been widely focused due to the advantages of abundant sodium resources, low price and similar properties to lithium. In the basic structure of sodium ion battery, the electrolyte determines the electrochemical window and electrochemical performance of the battery, controls the properties of the electrode/electrolyte interface, and affects the safety of sodium ion batteries. Organic liquid electrolytes are widely used because of their low viscosity, high dielectric constant, and compatibility with common cathodes and anodes. However, there are problems such as low oxidation potential, high flammability and safety hazards. Therefore, the development of novel, low-cost, high-performance organic liquid electrolytes is essential for the commercial application of sodium ion batteries. In this paper, the basic requirements and main classifications of organic liquid electrolytes for sodium ion batteries have been introduced. The current research status of organic liquid electrolytes for sodium ion batteries has been highlighted, including compatibility with various types of electrodes and electrochemical properties such as multiplicative performance and cycling performance of electrode materials in electrolytes. The composition, formation mechanism and regulation strategies of interfacial films have been explained. Finally, the development trends of sodium ion battery electrolytes in terms of compatibility with materials, safety and stable interfacial film formation are pointed out in the future.

Packed OV-SnO2-Sb bead-electrodes for enhanced electrocatalytic oxidation of micropollutants in water

Electrocatalytic oxidation is an appealing treatment option for emerging micropollutants in wastewater, however, the limited reactive surface area and short service lifetime of planar electrodes hinder their industrial applications. This study introduces an innovative electrochemical wastewater treatment technology that employs packed bead-electrodes (PBE) as a dynamic electrocatalytic filter on a dimensionally stable anode (DSA) acting as a current collector. By using PBE, the electroactive volume is expanded beyond the vicinity of the common planar anode to the thick porous media of PBE with a vast electrocatalytic surface area. This greatly enhances the efficiency of electrochemical degradation of micropollutants. The OV-SnO2-Sb PBE filter achieved a nearly 100 % degradation of moxifloxacin (MOX) in under 2 min of single-pass filtration, with a degradation rate over an order of magnitude higher than the conventional electrochemical oxidation processes. The generation of abundant radical species (•OH) and non-radical species (1O2 and O3), along with the enhanced direct oxidation, led to the outstanding performance of the charged PBE system in MOX degradation. The OV-SnO2-Sb PBE was remarkably stable, and the separation between the electroactive PBE layer and the base Ti anode allows for easy renewal of the bead-electrode materials and scaling up of the system for practical applications. Overall, our study presents a dynamic electroactive PBE that advances the electrocatalytic oxidation technology for effective control of emerging pollutants in the water environment. This technology has the potential to revolutionize electrochemical wastewater treatment and contribute to a more sustainable future environment.

Self-powered optical ion sensor array based on potentiometric probes coupled to electronic paper

This work describes a direct optical readout of an ion-selective potentiometric sensing array without an external power supply. Electronic paper (e-paper) was chosen as the signal transducer owing to its fast response on the order of seconds and its wide dynamic range of about 1.5 V. The capacitive character of the display allows one to observe the optical response at zero current, which is a desired condition for the potentiometric measurement. An applied potential of 1 V gives a transient charge flow of about 11 μC for the e-paper to exhibit a maximal intensity change. The cathodes of three different pixels of the e-paper were connected to three different ISEs responsive to Na+, K+, and Ca2+, while their common anode was connected to the shared reference electrode (RE). In this manner, each pixel is mapped to the behavior of one sensor, making it possible to detect multiple ions with an e-pixel array. The sensor configuration gave quantitative information on Na+, K+, and Ca2+ from 10−5 M to 10−1 M by analyzing the RGB information of the pixels. The e-paper exhibited a stable response within half a minute, much faster than previously established electrochromic material transducers such as Prussian Blue (PB). With this approach we successfully carried out multi-ion concentration sensing without external power, which is potentially attractive for applications in environmental monitoring, clinical assays and wearable sensing devices.

A multiband radio-frequency energy harvester for self-powered biosensor

This paper presents a novel nano-structure of radio frequency (RF) to direct current (DC) converter for the energy control unit in the biosensor. It is based on the Graëtz Bridge supplied with three-phase power (DP3). This circuit can be considered as the result of the proper combination of a common anode assembly and a common cathode assembly. In fact, the same three-phase converter structure was kept. The diodes have been replaced by six NMOS transistors connected in diodes. A number of capacitors have been added for each stage to boost voltage. The benefit of using this type of circuit is to obtain a powerful DC output signal with the smallest number of stages. The proposed architecture also enables MOS transistors to be driven by external 2.45 GHz voluntary signals originating from the implant's personal assistant. This would allow avoiding the use of transistor control circuits which are already power-consuming. For more power, the proposed converter receives two more involuntary global system for mobile signals (GSM) with 900 MHz and 1800 MHz frequencies bands in order to take advantage of the ambient energy. The proposed RF-DC converter efficiency reaches 62.8% for an input power equal to 10 dbm.

Conquering poor reversibility of zinc powder electrode through in-situ surface engineering towards long-life zinc-ion batteries

With the increasing popularity of aqueous zinc-ion batteries, extensive research has been dedicated to mitigating dendritic growth and parasitic reactions for zinc metal anodes. While zinc foil is currently used as a common anode, zinc powder (Zn-P) turns out to be a promising alternative. However, Zn-P is more prone to experience corrosion and induce hydrogen evolution due to its larger specific surface area, thereby resulting in poor cyclability for Zn-P-based batteries. In this study, a simple yet highly effective strategy is developed to modify Zn-P with in-situ formed indium metal protective layer that owns larger hydrogen evolution overpotential than zinc metal. The modified Zn-P is combined with nanocellulose and carbon black to form a composite electrode, which can effectively resist corrosion and hydrogen evolution, facilitate desolvation process, and promote zinc deposition kinetics. Thanks to that, the modified Zn-P realizes significantly improved cumulative zinc plating capacity of 500 mAh cm−2 during symmetric cell test and the assembled Zn//MnO2 battery achieves impressive capacity retention of 97.6% after 2000 cycles. Overall, the composite electrode not only outperforms its unmodified counterpart but also exhibits distinct advantages over previously reported Zn-P-based electrodes. This work reveals a universal pathway to modify metal powder electrodes towards high-performance batteries.

Integration of Cointercalation and Adsorption Enabling Superior Rate Performance of Carbon Anodes for Symmetric Sodium-Ion Capacitors.

Carbon materials have been the most common anodes for sodium-ion storage. However, it is well-known that most carbon materials cannot obtain a satisfactory rate performance because of the sluggish kinetics of large-sized sodium-ion intercalation in ordered carbon layers. Here, we propose an integration of co-intercalation and adsorption instead of conventional simplex-intercalation and adsorption to promote the rate capability of sodium-ion storage in carbon materials. The experiment was demonstrated by using a typical carbon material, reduced graphite oxide (RGO400) in an ether-solvent electrolyte. The ordered and disordered carbon layers efficiently store solvated sodium ions and simplex sodium ions, which endows RGO400 with enhanced reversible capacity (403 mA h g-1 at 50 mA g-1 after 100 cycles) and superior rate performance (166 mA h g-1 at 20 A g-1). Furthermore, a symmetric sodium-ion capacitor was demonstrated by employing RGO400 as both the anode and cathode. It exhibits a high energy density of 48 W h g-1 at a very high power density of 10,896 W kg-1. This work updates the sodium-ion storage mechanism and provides a rational strategy to realize high rate capability for carbon electrode materials.

Synergy of VN and Fe2O3 Enables High Performance Anodes for Asymmetric Supercapacitors.

Fe2O3 is one of the most common anode materials beyond carbons but suffers from unsatisfactory capacity and poor stability, which are associated with the insufficient utilization of active material and the structural instability caused by the phase transformation. In this work, we report an effective strategy to overcome the above issues through electronic structure optimization by constructing delicately designed Fe2O3@VN core-shell structure. The Fe2O3@VN/CC exhibits a much higher areal capacity of 254.8 mC cm-2 at 5 mA cm-2 (corresponding to 318.5 mF cm-2, or 265.4 F g-1) than the individual VN (48 mC cm-2, or 60 mF cm-2) or Fe2O3/CC (93.36 mC cm-2, or 116.7 mF cm-2), along with enhanced stability. Moreover, the assembled asymmetric supercapacitor devices based on Fe2O3@VN/CC anode and RuO2/CC cathode show a high stack energy density of 0.5 mWh cm-3 at a power density of 12.28 mW cm-3 along with good stability (80% capacitance retention after 14000 cycles at 10 mA cm-2). This work not only establishes the Fe2O3@VN as a high-performance anode material but also suggests a general strategy to enhance the electrochemical performance of traditional anodes that suffer from low capacity (capacitance) and poor stability.

MULTI-ELECTRODE TRANSCUTANEOUS ELECTRICAL STIMULATION OF THE HUMAN EXTERNAL EAR

This article reviews the development of a new concept for crafting and testing a multi-electrode set-up for selective transcutaneous auricular nerve stimulation (tANS) using particular superficial regions of the external ear (EE). The purpose of the work is to assess the mechanical properties of the set-up to ensure the optimum conditions for the users, and to test the ability to affect vital physiological functions. The set-up consisted of eight cap-like platinum simulating cathodes (S = 14.58 mm2) that were embedded in the left and right silicone ear plugs. The plugs were mounted onto the frame of dummy headphones and inserted into the EE, while a common anode (anode) (S = 4500 mm2) was placed at the nape of the neck. The mechanical performance was assessed by measuring the axial force Fx acting on each cathode against the bending of the dummy headphone frame while simulating the conditions of the set-up being mounted onto the head. The functionality was tested by applying stimuli onto four predefined sites at the EE to modify particular vital physiological functions of female volunteers. The preliminary results show that during the tANS, the bi-nasal respiration became shorter but more frequent with steeper inspiration and a lower airflow. The results also show that during the tANS, the heart rate was slightly diminished along with the respiratory sinus arrhythmia. Finally, a dicrotic notch within the toe photoplethysmogram was masked by the waves with a frequency of approximately 300 min–1. The presented work has implications for the multi-electrode set-up design and the prediction of efficient tANS used to modify physiological functions.

Sodium Diffusion in Hard Carbon Studied by Small- and Wide-Angle Neutron Scattering and Muon Spin Relaxation

Hard carbon is the most common anode material for Na-ion battery. The structure of the hard carbon and the dynamics of Na-ion in hard carbon were studied with small- and wide-angle neutron scattering and muon spin relaxation technique. The neutron scattering revealed the increase of interlayer distance between graphenes and decrease of the size of nanopores with increasing sodium intercalation in hard carbon. The muon spin relaxation revealed that a systematic increase in the field fluctuation rate with increasing temperature evidenced a thermally activated sodium diffusion. Assuming the two-dimensional diffusion of Na-ion in the graphene layers, the self-diffusion coefficient of Na-ion was estimated to be 2.6 × 10−11 cm2/s at 310 K, with a thermal activation energy of 39(7) meV.

Detailed Study of Sulfur Poisoning and Recovery of Ni-YSZ-Based Anodes Operating up to 1.8 W cm-2 in a Biogas Fuel

Ni-YSZ (nickel-yttrium-stabilized zirconia) is a common anode for solid oxide fuel cells (SOFCs) because of its excellent catalytic performance and electronic conductivity. It shows that the nickel anode-supported cell exhibits good cell performance in a biogas fuel of 36CH4-36CO2-20H2O-4H2-4CO. Unfortunately, natural biogas fuels often contain sulfur, so using nickel anodes is not always straightforward. This paper investigates the sulfur poisoning and the recovery of BaCe0.7Zr0.1Y0.1Yb0.1O3-δ- (BCZYYb-) (Ce, Y, and Yb codoped barium zirconate) impregnated nickel anode-supported cells operating up to 1.8 W cm-2 in the biogas. The in situ gas analysis reveals that the suppression of the reforming reactions might cause sulfur poisoning in a 4 ppm (v) H2S (hydrogen sulfide) in open circuit conditions, whereas the current degradation in working conditions could be attributed to the deactivation of reforming reactions and catalyst activity. The incidence of water-gas shift reactions is associated with the degradation rate of these two reactions. After removing the H2S, the recovery is accelerated by a steam hydrogen fuel, indicating that steam facilitates the efficient release of sulfur from nickel sites.

The intrinsic electrostatic dielectric behaviour of graphite anodes in Li-ion batteries—Across the entire functional range of charge

Lithium–graphite intercalation compounds (Li-GICs) are by far the most common anode material for modern Li-ion batteries. However, the dielectric response of this material in the electrostatic limit and its variation depending on the state of charge (SOC) has not been investigated to a satisfactory degree – neither by means of theory nor by experiment – and especially not for the higher range of SOC. In this work, we – for the first time – predict a mostly linear dependency of the relative permittivity ϵr on the SOC, from ≈7 at SOC 0% to ≈25 at SOC 100%. This is achieved by making use of our recently published DFTB parametrization for Li-GICs based on a machine-learned repulsive potential in order to overcome the computational hurdles of sampling the long-ranged Coulomb interactions within this material. In doing so, we provide novel insight into a property which is highly desired, particularly as an input parameter for charged kinetic Monte Carlo simulations.
