Abstract

We report on multiphysics full-wave techniques in the frequency (energy)-domain and the time-domain, aimed at the investigation of the combined electromagnetic-coherent transport problem in carbon based nano-structured materials and devices, e.g. graphene nanoribbons. The frequency-domain approach is introduced in order to describe a Poisson/Schroedinger system in a quasi static framework. An example about the self-consistent solution of laterally coupled graphene nanoribbons is shown. The time-domain approach deals with the solution of the combined Maxwell/Schroedinger system of equations. We deal with i) the very challenging problem of he analysis of charge injection from metal to a contacted graphene nanoribbon (GNR); ii) a first prototype of graphene-based patch antenna.
