We have predicted a novel class of 2D wide-bandgap InTeI layered semiconductors, which high stability, tunable electronic property, and ultra-high anisotropic carrier mobility.
Two-dimensional (2D) GaInS3 nanosheets are found to exhibit thermal and structural stabilities, good oxidation resistance, tunable layer-dependent electronic properties from first-principles calculations. Remarkably, the with arbitrary thickness possess robust in-plane piezoelectricity without odd-even effect commonly observed in other 2D piezoelectric materials, which is attributed retention of noncentrosymmetry resulting their homogeneous direct stacking patterns.

Low-dimensional materials have aroused widespread interest for their novel and fascinating properties. Based on first-principles calculations, we predict the one-dimensional (1D) InSeI nanochains with van der Waals (vdW) interchain interactions, which could be exfoliated mechanically kept at steady states room temperature.

Abstract Renewable energy‐driven electroreduction of nitrate to ammonia presents a low‐carbon and promising route for sustainable synthesis. For Cu‐based electrocatalysts, due their sluggish kinetics the hydrogenation steps, nitrite often accumulates on electrocatalysts surface, resulting in low yield rate selectivity, as well serious deactivation electrocatalysts. Herein, continuous relay site construction strategy that integrates Cu─Co sites into an interconnected porous network is...
