We present a Monte Carlo simulator for RF graphene FETs including the dominant scattering mechanisms and a simple model for band-to-band tunneling. We found that in state-ofthe- art devices scattering is relevant and degrades the cut-off frequency compared to the predictions of ballistic models.

Abstract
We present a Monte Carlo simulator for RF graphene FETs including the dominant scattering mechanisms and a simple model for band-to-band tunneling. We found that in state-ofthe- art devices scattering is relevant and degrades the cut-off frequency compared to the predictions of ballistic models.File in questo prodotto:
