Modeling of Tunnel Field Effect Transistor - the impact of construction parameters

The aim of the work is to present a theoretical model of tunnel field effect transistor and to investigate the influence of the TFET's construction parameters on the current-voltage characteristics. The solution to the problem of electrostatics in the structure is based on the numerical solution of two-dimensional Poisson equation and the electron and hole continuity equations. The tunneling process has been taken into account by a non-local interband generation model. Output and transfer characteristics of the double gate TFET were generated.
