Engineering the flexibility of graphene/h-BN lateral heterojunctions

Abstract

Abstract Employing the first-principles calculations, the mechanical properties of graphene/hexagonal boron nitride (h-BN) lateral heterojunctions were studied, including the Young’s modulus and bending modulus. It was found that by varying the ratio of graphene in the graphene/h-BN heterojunction, both the Young’s modulus and bending modulus of can be effectively engineered. Particularly, the bending modulus increases with the ratio of graphene to h-BN, providing a way to tailor the flexibility of two-dimensional materials.
