Stabilization of highly polar BiFeO${}_3$-like structure: a new interface design route for enhanced ferroelectricity in artificial perovskite superlattices

Hongwei Wang, Jianguo Wen, Dean J. Miller +5

In ABO3 perovskites, oxygen octahedron rotations are common structural distortions that can promote large ferroelectricity in BiFeO3 with an R3c structure [1], but suppress ferroel…
