2D nanoelectronics: From graphene to silicene and beyond

This research work describes progress towards 2D nanoelectronics based on atomic sheets such as graphene, M0S2, black phosphorus, silicene and related materials. These diverse 2D nanomaterials can afford a wide range of device capabilities including low-power transistors, high-speed devices, zero-power switches, and wearable sensors. In addition, silicene, the atomically-thin equivalent of bulk silicon is predicted to be a topological insulator and in conjunction with related Xene sheets, can enable low-energy topological bits as a paradigm-shift for computation.
