Strain Engineering of Electronic, Elastic, and Optical Properties of a Pentagonal As 2 Ge Monolayer: A Density-Functional Theory Study
Within the framework of density-functional theory based first-principles calculations, the structural, electronic, and optical properties of the As 2 Ge monolayer have been investigated under uniaxial and biaxial strains with varying magnitudes. It has been found that the As 2 Ge monolayer exhibits ultimate strai...
