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… Show more
The emergence of van der Waals (vdW) heterostructures, which consist of vertically stacked two-dimensional (2D) materials held together by weak vdW interactions, has introduced an innovative avenue for tailoring nanoelectronic...
Herein, we design a metal–semiconductor heterostructure combining metallic TaSe2 and semiconducting WSe2 materials and investigate its atomic structure, electronic properties and controllable contact types using first-principles calculations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
