The Parametric Study of Armchair Graphene Nanoribbon Field Effect Transistor by Non-Equilibrium Green’s Function Method

We have carried out a comprehensive parametric analysis on the potential performance of a graphene nanoribbon field effect transistor (GNRFET). We modeled the behavior of GNRFETs with nanometer width GNR channels to formulate a self-consistent, non-equilibrium Green's function (NEGF) scheme in conjunction with the Poisson equation and allow the GNRFET to operate as a switch. Based on the results, we propose a metric to compete with current silicon CMOS highperformance (HP) or low-power (LP) devices, explaining that this can vary widely depending on the GNRFET structure parameters.
