How tiny misalignments in encapsulated graphene lead to a strong modification of its electronic properties

Researchers explain how a higher order periodic modulations due to the encapsulation of graphene between hexagonal boron nitride, called supermoire, affects the electronic and structural properties of graphene, as revealed in three recent independent experiments. High quality graphene samples are of high importance for obtaining and exploiting its theoretically described properties. Utilizing an adequate substrate reduces the corrugation and improves otherwise disorder limited properties of graphene.
