Abstract :
In this paper, asymmetric gate structure and pocket source are proposed into the double-gate tunneling FET (DG TFET). Steeper average subthreshold swing (SS) and larger on currents are observed in the proposed TFET as compared with conventional TFET. The improvements are attributed to a larger volume tunneling due to the enhanced body electric field. In addition, threshold voltage adjustment is achieved by adjusting the pocket source thickness, which indicates the potential for supply voltage scaling.
