Investigation in double layer graphene superlattice and its electronic properties

This paper mainly discussed the graphene and other 2D materials, as well as their electronic properties. The history and theory prediction of graphene, and production of graphene (mechanical exfoliation and CVD method) are discussed. Graphene hBN superlattice and bi-layer graphene superlattice are presented, with following discussion of the superconductivity of the magic angle. Finally, characterization methods such as AFM and SEM are presented.
