Negative Capacitance Tunnel Field Effect Transistor: A Novel Device with   Low Subthreshold Swing and High ON Current
  In this paper we propose a modified structure of TFET incorporating ferroelectric oxide as the complementary gate dielectric operating in negative capacitance zone, called the Negative Capacitance Tunnel FET (NCTFET). The proposed device effectively combines two different mechanisms of lowering the sub threshold swing (SS) for a transistor garnering a further lowered one compared to conventional TFET. A simple yet accurate analytical tunnel current model for the proposed device is also presented here. The developed analytical model demonstrates high ON current at low $V_{GS}$ and exhibits lower SS.
