Effect of Curie Temperature on Ferroelectric Tunnel FET and Its RF/Analog Performance

In this article, a numerical simulation study for the ferroelectric gate oxide tunnel field-effect transistor (Ferro-TFET) has been presented. The performance of the device is analyzed following Landau's theory and its behavior in the temperature range of 200-300 K. A minimum subthreshold swing and maximum transconductance is obtained around the Curie temperature ( T
_C
) of 580 ± 10 K for the simulated device. The simulation result is supported by the simple analytical model. The temperature sensitivity analysis is studied on different analog and RF figure of merits for Ferro-TFET. In this study, the Ferro-TFET shows the remarkable result in reducing the detrimental effect of mobility degradation at high gate voltage and performance degradation at high temperatures as compared to conventional TFETs and MOSFET. Therefore, at Curie temperature, the operation of the Ferro-TFET shows the remarkable results for analog and RF applications.
