First principles study of BAs/MoSi₂N₄ van der Waals heterostructure: tunable electronic and optical properties via vertical strain

Abstract

We use first-principles calculations to explore the modulation of a two-dimensional BAs/MoSi2N4 van der Waals heterostructure via strain, including the structure stabilities, electronic properties, charge transfer and optical properties.
