Graphene offers new opportunities for the optimization of high frequency FETs by virtue of high carrier velocity, excellent scaling properties, configurability as electron or hole channel devices, and limited scattering. The saturation velocity (vsat) of graphene has not been determined clearly yet, but it is estimated to be ∼5 times greater than that for Si MOSFETs [1]. With large on-state current density and transconductance per gate capacitance compared to Si, [2] graphene has the potential… CONTINUE READING
