Simulation of the suggested device is done based on non-equilibrium Green’s function (NEGF) method by a mode-space approach. Simulation results show that, compared to the conventional GNR-TFET, the BE-GNR-TFET enjoys from a better am-bipolar behavior and a higher on-current. Besides, the analog characteristic of the proposed structure such as transconductance (gm) and unity-gain frequency (ft) is also improved.
