In this paper, we reported electronic structures of monolayer graphene sandwiched by monolayer hexagonal boron nitride (hBN) using density functional theory. Our calculations show that the electronic structure of monolayer graphene is sensitive to the relative interlayer atomic arrangement. Monolayer graphene sandwiched by hBN possesses a finite bandgap at the K point when they have particular stacking arrangement. The gap gradually increases/decreases under sliding displacements. Therefore, hBN may affect the electronic structure of encapsulated atomic layer materials.
