"Numerical simulation of the electrical behavior of Carbon Nanotubes"

-Abstract
We introduce in an elementary way the physical setting used to model the electrical behavior of metallic Carbon Nanotubes (CNTs); our aim is to compute the current induced in a CNT by an external electrical field. In the proposed setting, the temporal evolution of electrons and phonons (the last ones needed to take into account quantum mechanics effects) is described by a system of Boltzmann Equations, a system of hyperbolic equations with collision terms. We will give an overview of the general theory on the numerical treatment of such type of equations and present two schemes with some details.
