Tuning of the electronic, photocatalytic and optical properties of Janus XWAZ2 (X = S, Se, Te; A = Si, Ge; Z = N, P, As) monolayers via strain and external electric field

Abstract

Explored the effects of biaxial strain and applied electric field on the electronic, optical, and photocatalytic properties of XWAZ2 monolayers using density functional theory based on first principles.
