Abstract
MXenes, an emerging class of two-dimensional materials, exhibit characteristics that promise significant potential for their use in next generation optoelectronic sensors. An interplay between interband transitions and boundary effects offer the potential to tune the plasma frequencies over a large spectral range from the near-infrared to the mid-infrared. This tuneability along with the ‘layered’ nature of the material not only offer the flexibility to produce plasmon resonances across a wide range of wavelengths, but also add a degree of freedom to the sensing mechanism by allowing the plasma frequency to be modulated. Here we show, numerically, that MXenes can support plasmons in the telecommunications frequency range and that surface plasmon resonances can be excited on a standard MXene coated side polished optical fiber. Thus, presenting the tantalising prospect of highly selective distributed optical fiber sensor networks.
Highlights
Two dimensional (2D) materials are a class of nanomaterials that exhibit unique physical properties due to quantum confinement effects associated with their 2D nature
Inspired by the interesting opportunities that MXenes can offer in different technologies, in this work we explore the possibility of using MXenes to support resonant surface plasmons polaritons (SPPs) on the side-polished optical fiber platform at telecommunications wavelengths
The excited SPPs can exist traveling along the z axis with the electric and magnetic fields being along the (z,y) and (x) axis, respectively
Summary
Two dimensional (2D) materials are a class of nanomaterials that exhibit unique physical properties due to quantum confinement effects associated with their 2D nature. Their combined superlative electronic, mechanical, and optical properties have been the driving force behind the ongoing and intense study into their applicability for opto/electronic, sensing, and energy-related applications[1,2,3]. MXenes are, the largest subclass of 2D materials, their physical properties are highly tuneable due to their variable chemistry[4]. MXenes nanosheet are hydrophilic and can form stable colloidal dispersions[6].
