Two-dimensional graphene electronics: current status and prospects

Graphene, a two-dimensional carbon material, is reviewed for how it is currently used in nanometer-scale electronics (nanoelectronics). The history of the discovery of graphene is briefly described. Theoretical work on graphene heterostructures is examined. The primary focus is on the practical use of graphene in nanoelectronics applications. Prospects for graphene and post-graphene nanoelectronics are discussed.
