Using a ferroelectric gate stack, the range of the steep subthreshold swing of FET-elde-ect transistors was extended and improvement in the swing. The ferroelectric negative capacitance e-ect bene-cial to voltage ampli-cation with transconductnace 118% and channel conductance 16%. The concept of coupling the ferroelectric polarization is proposed for low-power applications of steep subthreshold slope devices.
