Tunnel FETs (TFETs) have attracted much interest in the last decade for their potential to be used as small slope switches, suitable for future logic circuits operating with a supply voltage smaller than 0.5 V and for reduced Ioff levels. It has been shown ...

The performance of a standard MOSFET degrades with the increase in temperature, impacting the power consumption of the device. In this paper, we report the opposite trend, which is reflected in an improvement of main performance factors in ferroelectric FE ...
