Steep slope negative capacitance FET (NCFET) has been a promising candidate as new CMOS platform for future IoT technology. In this work, we have proposed an NCFET with ferroelectric HfO₂ thin film. We have provided device design guideline for hysteresis-free and highly energy-efficient NCFET at less than Vdd 0.2V to determine optimum ferroelectric material parameters.
