Paraelectric-Ferroelectric Transition in Hafnium-Oxide-Based Ferroelectric Memory

In this work, we report the paraelectric-ferroelectric transition of the ferroelectric HfZrO with buffered HfNO. Our experimental and simulated results reveal that the buffered HfNO plays a key role in paraelectric-ferroelectric switching and ferroelectric recovery during cycled switching. The transient current pulse measurement was employed to verify the switching mechanism.
