Abstract

A hydrodynamical model for the charge and the heat transport in graphene is presented. The state variables are moments of the electron, hole and phonon distribution functions, and their evolution equations are derived from the respective Boltzmann equations by integration. The closure of the system is obtained by means of the maximum entropy principle and all the main scattering mechanisms are taken into account. Numerical simulations are presented in the case of a suspended graphene monolayer.

Abstract

A hydrodynamical model for simulating charge transport in graphene nano-ribbons is formulated by using of the maximum entropy principle (hereafter MEP). Both electrons in the conduction band and holes in the valance bands are considered and it is assumed a linear dispersion relation for the energy bands around the equivalent Dirac points. The closure relations do not contain any fitting parameters except the ones already present in the kinetic description.
