Interface control of ferroelectricity in LaNiO3-BaTiO3 superlattices
LaNiO3-BaTiO3 superlattices with different types of interfaces are studied from first-principles density-functional theory. It is revealed that the ferroelectricity in the superlattice with (NiO2)−/(BaO)0 interfaces is enhanced from that of the superlattice with (LaO)+/(TiO2)0 interfaces. The origin...
