Origin of Suppressed Ferroelectricity in k-Ga${}_2$O${}_3$: Interplay Between Polarization and Lattice Domain Walls

Yonghao Zhu, Zhi Wang, Junwei Luo +1

The large discrepancy between experimental and theoretical remanent polarization and coercive field limits the applications of wide-band-gap ferroelectric materials. Here, using a…
