A 2-D Analytical Model for Double-Gate Tunnel FETs

This paper presents a 2-D analytic potential model for double-gate (DG) tunnel field effect transistors (TFETs) by solving the 2-D Poisson's equation. From the potential profile, the electric field is derived and then the drain current expression is extracted by analytically integrating the band-to-band tunneling generation rate over the tunneling region. The model well predicts the potential, subthreshold swing (SS), and transfer and output characteristics of DG TFETs. We analyze the… CONTINUE READING
