Band gap formation in commensurate twisted bilayer graphene/hBN moiré lattices
Band gap formation in commensurate twisted bilayer graphene/hBN moiré lattices
We report on the investigation of periodic superstructures in twisted bilayer graphene (tBLG) van der Waals heterostructures, where one of the graphene layers is aligned to hexagonal boron nitride (hBN). Our theoretical simulations reveal that if the ratio of the resulting two moir\'e unit-cell areas is a simple fraction, the …
