Fastest Graphene Transistor Yet
New progress in the blossoming field of graphene-based electronics comes from IBM researchers, who report the creation of a graphene transistor that operates at 26 GHz, the highest frequency yet achieved (Nano Lett., DOI: 10.1021/nl803316h). The researchers also show that the performance of these transistors increases as the device's size decreases. Graphene, a chicken-wire-structured sheet of carbon, has drawn much attention for its tantalizing electronic properties: . . .
