Graphene and beyond-graphene 2D crystals for next-generation green electronics

In this paper, we first review the impressive properties of two-dimensional (2D) nanocrystals, primarily graphene and beyond-graphene 2D crystals, such as transition-metal dichalcogenides (TMDs), and then highlight some applications uniquely enabled by these materials for designing next-generation low-power and low-loss "green electronics". Key challenges of 2D crystals relevant to such applications are discussed as well.
