Simulation of graphene nanoribbon interconnects by boltzmann-poisson approach under relaxation time approximation

Abstract

An effective approach for simulating electronic transport in graphene nanoribbon (GNR) interconnects is presented based on the Boltzmann-Poisson formalism. The Boltzmann transport equation (BTE) is solved under the relaxation time approximation (RTA). Using this method, the current-voltage (I-V) characteristics of metallic GNRs are investigated in detail. The proposed method can provide accurate prediction of I-V characteristics of GNR interconnects.
