Domain wall reactions in multiple-order parameter ferroelectrics
Songsong Zhou, Shihan Qin, Andrew M. Rappe
The motion of domain walls is crucial for ferroelectric switching. Conventionally, the switching dynamics is believed to be determined by the motion of one or a few low-energy doma…

Nucleation mechanism of multiple-order parameter ferroelectric domain wall motion in hafnia
Songsong Zhou, Andrew M. Rappe
Ferroelectric hafnia exhibits promising robust polarization and silicon compatibility for ferroelectric devices. Unfortunately, it suffers from difficult polarization switching. Me…
