Physics-Based Compact Modeling of Double-Gate Graphene Field-Effect Transistor Operation Including Description of Two Saturation Modes

Abstract: Based on diffusion-drift approximation a version of analytic compact model for large-area double-gate graphene field-effect transistor is presented. As parts of the model, the electrostatics of double-gate structure is described and a unified phenomenological approach for modeling of the two drain current saturation modes is proposed.
