Large remnant polarization in a wake-up free Hf0.5Zr0.5O2 ferroelectric film
Alireza Kashir, Hyung Woo Kim, Seungyeol Oh +1
A wake-up free Hf0.5Zr0.5O2 (HZO) ferroelectric film with the highest remnant polarization (Pr) value to-date was achieved through tuning of the ozone pulse duration, the annealing…

Defect engineering for control of wake-up effect in HfO2-based ferroelectrics
Alireza Kashir, Seungyeol Oh, Hyunsang Hwang
Wake-up effect is still an obstacle in the commercialization of hafnia-based ferroelectric thin films. In this work, we investigate the effect of defects, controlled by ozone dosag…
