Simulation of the Performance of Graphene FETs With a Semiclassical Model, Including Band-to-Band Tunneling

We assess the analog/RF intrinsic performance of graphene FETs (GFETs) through a semiclassical transport model, including local and remote phonon scattering as well as band-to-band tunneling generation and recombination, validated by comparison with full quantum results over a wide range of bias voltages. We found that scaling is expected to improve the fT, and that scattering plays a role in redu...
