Does carrier velocity saturation help to enhance <i>f</i><sub>max</sub> in graphene field-effect transistors?
It has been argued that current saturation in graphene field-effect transistors (GFETs) is needed to get the highest possible maximum oscillation frequency (fmax). This paper numerically investigates whether velocity saturation can help to get better current saturation and if that correlates with enhanced fmax. For such a purpose, we used …
