Abstract

We develop a numerical model for simulation of plasmons in graphene with grating-gate structures, based on the Boltzmann equation and self-consistent Poisson equation. Using the model, we study the effect of coupling between plasmons in gated and ungated regions on the frequency tunability by the gate voltage and the damping of plasmons due to carrier scattering and due to source and drain contacts.
