Calculation of Quantum Capacitance and Sheet Carrier Density of Graphene FETs
We have done a simulation study on the quantum capacitance and sheet carrier density of graphene MOSFETs following a quasianalytical model for graphene MOSFET with gapless large area graphene channel (Thiele et al. in JAP 107:094505, 2010 ). First, the simulation model has been validated by properly reproducing the values of quantum capacitance for a graphene MOSFET without back-gate and zero applied drain-source voltage. Next, we have investigated the effect of both top-gate and back-gate voltages on the quantum capacitance and sheet carrier density and the results are presented here.
