Metal oxide semiconductor field-effect transistor (MOSFET) has an important role in electric circuits because of its nano-size. However, MOSFETs have performance limitations to work in ultra-low power, leaky currents, short channel effects, and increased speed. These performance limitations make the tunneling field-effect transistor (TFET) an alternative to replace the MOSFET. In this study, a drain current on devices based on bilayer armchair graphene nanoribbon (BAGNR) was modeled using the Airy function approach. Solving the Schrödinger equation with the Airy function approach produces a transmittance value, and therefore the drain current value can be determined using the Launder formula with the Gauss Legendre Quadrature (GLQ) method. The results of the modeling show that the drain current value increases with the increasing gate voltage (Vg), drain voltage (Vd) and width of BAGNR, while the increase in oxide thickness and temperature decreases the drain current.
