Cataloguing MoSi₂N₄ and WSi₂N₄ van der Waals Heterostructures: An Exceptional Material Platform for Excitonic Solar Cell Applications (Adv. Mater. Interfaces 2/2023)

Abstract

van der Waals Heterostructures MoSi2N4 and WSi2N4 monolayers have recently emerged as promising 2D semiconductors for solid‐state device applications. In article number 2201856 by Guangzhao Wang, Yee Sin Ang, and colleagues, 51 species of MoSi2N4‐and WSi2N4‐based van der Waals heterostructures are comprehensively catalogued using first‐principle simulations. These heterostructures are found to exhibit exceptional electronic and optical properties, thus unravelling their enormous potential as building blocks of high‐performance solar cell and UV optoelectronic device technology.
