Design of bilayer graphene nanoribbon tunnel field effect transistor

Purpose The purpose of this paper is to design novel tunnel field effect transistor (TFET) using graphene nanoribbons (GNRs). Design/methodology/approach To design the proposed TFET, the bilayer GNRs (BLGNRs) have been used as the channel material. The BLGNR-TFET is designed in QuantumATK, depending on 2-D Poisson’s equation and non-equilibrium Green’s function (NEGF) formalism. Findings The performance of the proposed BLGNR-TFET is investigated in terms of current and voltage (I-V) characteristics and transconductance. Moreover, the proposed device performance is compared with the monolayer GNR-TFET (MLGNR-TFET). From the simulation results, it is investigated that the BLGNR-TFET shows high current and gain over the MLGNR-TFET. Originality/value This paper presents a new technique to design GNR-based TFET for future low power very large-scale integration (VLSI) devices.
