Abstract :
In this paper, we have proposed the new structure of T-FET and analyzed the impact of spacer dielectric, device width, metal electrodes and temperature on Tunnel Field Effect Transistor (T-FET). A numerical TCAD device simulator 3-D ATLAS version 2.10.18.R shows that reducing the width will reduce the effective threshold voltage. Transistor with a high ION /IOFF ratio of 1010 sub-threshold swing of 54 mV/dec for the channel length of 50 nm with Hafnium oxide as gate dielectric material of thickness 3 nm and spacer dielectric as the silicon dioxide material.
