Stabilization of Highly Polar BiFeO_{3}-like Structure: A New Interface Design Route for Enhanced Ferroelectricity in Artificial Perovskite Superlattices
In ABO_{3} perovskites, oxygen octahedron rotations are common structural distortions that can promote large ferroelectricity in BiFeO_{3} with an R3c structure [1] but suppress ferroelectricity in CaTiO_{3} with a Pbnm symmetry [2]. For many CaTiO_{3}-like perovskites, the BiFeO_{3} structure is a...
