Hysteresis Reduction in Negative Capacitance Ge PFETs Enabled by Modulating Ferroelectric Properties in HfZrOx

open access: yesIEEE Journal of the Electron Devices Society, 2018
We experimentally demonstrate that hysteresis of negative capacitance (NC) Ge pFETs is reduced through modulating the ferroelectric properties in HfZrOx (HZO) by changing the post annealing temperature. As annealing temperature varies from 350 °C to 450 °
