Abstract

In this work, we investigated the negative capacitance (NC) effect of ferroelectric HfAlO on the poly-silicon thin film transistor devices using high-\kappa HfO₂ gate insulator by simulation. Excellent performances were achieved, including a high on-state drive current, a high I_on/I_off of \gt10{7} and a low subthreshold swing of 58 mV/dec. These enhanced performances were related to the strong ferroelectric polarization inducing NC effect to obtain excellent gate controllability.
