Tunnel Field Effect Transistor

In this paper, the dc performance of a double gate Junctionless Tunnel Field Effect Transistor (DG-JLTFET) has been further enhanced with the implementation of double sided nonuniform Gaussian doping in the channel. The device has been simulated for different channel materials such as Si and various III-V compounds like Gallium Arsenide, Aluminium Indium Arsenide and Aluminium Indium Antimonide. It is shown that Gaussian doped channel Junctionless Tunnel Field Effect Transistor purveys higher ION/IOFF ratio, lower threshold voltage and sub-threshold slope and also offers better short channel performance as compared to JLTFET with uniformly doped channel.

Abstract Temperature-induced performance variation is one of the main concerns of the conventional stack gate oxide double gate tunnel field-effect transistor (SGO-DG-TFET). In this regard, we investigate the temperature sensitivity of extended source double gate tunnel field-effect transistor (ESDG-TFET). For this, we have analyzed the effect of temperature variations on the transfer characteristics, analog/RF, linearity and distortion figure of merits (FOMs) using technology computer aided design (TCAD) simulations. Further, the temperature sensitivity performance is compared with conventional SGO-DG-TFET. The comparative analysis shows that ESDG-TFET is less sensitive to temperature variations compared to the conventional SGO-DG-TFET. Therefore, this indicates that ESDG-TFET is more reliable for low-power, high-frequency applications at a higher temperature compared to conventional SGO-DG-TFET.
