Abstract

Objectives: This paper presents the review of Tunnel FET (TFET) to overcome the major challenges faced by the conventional MOSFET. Analysis: Various device structures and characteristics of TFET along with different material and doping to improve efficiency are discussed in detail. In recent years, TFET seems to be an attractive device for analog/ mixed-signal applications due to their advantages such as high ON current (ION), low leakage current (IOFF), reduced values of threshold voltage (VT) and low Subthreshold Swing (SS).
