Evaluation of electrical performance of various tunnel TFETs

Abstract

Tunnel field-effect transistor (TFET) is a promising device which has extraordinary performance on subthreshold swing and is feasible for ultralow power applications. However, one of the main factors of power dissipation and circuit delay among different designs of TFET, namely, parasitic capacitances, has not been discussed in detail. In this paper, parasitic capacitance of various types of TFETs are simulate and analyze.
