We describe a numerical method suitable to understand transport in graphene p-n-p structures. Our approach is based on a simplified electrostatic model and on an envelope-function based transport code. In particular, we have been able to model Fabry-Pérot resonances in the potential cavity defined by the double junction and to reproduce existing data of scanning gate conductance spectroscopy.

Abstract
We describe a numerical method suitable to understand transport in graphene p-n-p structures. Our approach is based on a simplified electrostatic model and on an envelope-function based transport code. In particular, we have been able to model Fabry-Pérot resonances in the potential cavity defined by the double junction and to reproduce existing data of scanning gate conductance spectroscopy.File in questo prodotto:
