Effect of layer sliding on the electronic and optical properties of corrugated silicene/indium selenide van der Waals heterostructure

Structural, electronic and optical properties of two dimensional corrugated silicene/InSe heterostructure have been calculated using density functional theory. The effect of layer sliding on the aforementioned physical properties is also studied. The maximum value of energy barrier along the sliding pathway is found to be 0.051 eV. To elucidate the electronic nature at the interface of the heterostructure, several interfacial properties have been discussed. Our employed strategy advocates that through layer sliding physical properties of a material can be tuned in a controlled manner.
