Entropy-modulated atomic ripple texturing in two-dimensional transition metal carbonitrides

Periodically atomic displacement in two-dimensional (2D) ripple texturing offers a promising route for selective modulation of local potential, crucial for advanced electronic engineering. However, in 2D transition metal carbonitrides (MXenes), the construction and regulation of atomic ripples to control electronic properties meet substantial challenges due to the difficulty in tailoring homogeneous deformation. Here, we propose a competition strategy that leverages configurational entropy and surface termination to controllably modulate the atomic ripple structure within Nb2CTex-based Mxenes. This chemical disorder releases the local in-plane strain induced by termination atoms with large ionic radii, thus enabling the regulation of out-of-plane atomic displacement. The deliberate design of the ripple structure regulates the dielectric relaxation time of the microscopic dipole in the electric field. Consequently, high-entropy MXenes deliver strong intensity of microwave absorption (−41.12 dB) and an absorption bandwidth of nearly 10 GHz, covering the S-, C-, and X-bands. This study establishes the relationship between atomic ripple structure, atomic strain, polarization relaxation, and dielectric properties, providing guidance for designing advanced MXenes materials for various applications.

Nano‐Heterointerface Coupling Engineering Induced Electromagnetic Response by Tailored Spindle Arrays for Microwave Absorption

Abstract Heterointerface coupling engineering derived from nanoscale heterostructures represents a promising approach to developing high‐performance electromagnetic functional materials, but the underlying mechanism of the heterointerface coupling for microwave absorption remains unclear. In this work, nano‐interfaces and dielectric/magnetic heterostructures are designed and customized in multilevel spherical architecture with graphitized carbon core and Fe3O4 shell (C/Fe3O4) in tailored spindle arrays by an in situ reduction process. Results from electron holography and COMSOL multiphysics simulation demonstrate that high‐density nano‐interfaces exhibit impressive heterointerface coupling and induce strong polarization relaxation. The spatial distribution of Fe3O4 nanoparticles constructs multiscale magnetic coupling networks, which enhance interactions with incident microwaves and improve magnetic loss capability. Furthermore, the coupling mechanisms of the dielectric/magnetic heterostructures and heterointerface for the microwave absorption are systematically investigated. The as‐prepared C/Fe3O4 spherical heterostructures exhibit remarkable electromagnetic absorption performance, achieving a maximum refection loss of ‐40.1 dB and an effective absorption bandwidth of 5.12 GHz at a thickness of 2.0 mm. This finding not only reveals the intrinsic loss mechanisms of nano‐heterointerface coupling but also provides a new strategy for constructing multilevel hollow heterostructures.
