[20p-A200-4] Evaluation of h-BN crystals in terms of its influence on adjacent graphene
Keywords:h-BN, van der Waals heterostructure, graphene
Hexagonal boron nitride (h-BN) is the only insulating layered material having a bandgap of ~6 eV. It is widely used as an atomically flat substrate, capping layer, and insulating layer for van der Waals heterostructures. We evaluated the quality of h-BN single crystals by measuring the transport properties of graphene deposited on exfoliated h-BN flakes.
