Abstract
The Tunnel-FET (TFET) device is a gated reverse biased p-i-n junction whose working principle is based on the quantum mechanical Band-to-Band Tunneling (B2BT) mechanism [1]. The OFF-ON transition can be much more abrupt than for conventional MOSFETs, thus allowing a reduction of the supply voltage and power consumption in logic applications [2]. Several TFETs with point Subthreshold Swing (SS) lower than 60mV/dec have been experimentally demonstrated with different architectures as conventional single gate Silicon-on-Insulator (SOI), Double Gate (DG) and Gate-All-Around (GAA) [3,4]. Unfortunately in all cases a relatively large average SS and a poor on-current have been observed.
