Paper Abstract

In this paper, the impact of varying the dielectric constant of the gate dielectric on the device performance of a double gate p-channel tunnel field-effect transistor (p-TFET) is reported for the first time. It is observed that fringing field arising out of a high−κ gate dielectric degrades the device performance of a p-TFET, which is in contrast with its nchannel counterpart, where the same been reported to yield better performance. Also, the impact of fringing field is found to be larger for a p-TFET with higher source doping.
