Emergent New Electronic Properties in Atomic Layer Complex Oxide Superlattices

Complex oxides exhibit a plethora of collective phenomena such as ferroelectricity, magnetism and superconductivity. They have been widely studied both in bulk and thin film form. Advances in synthesis techniques have enabled the formation of atomically precise interfaces between isostructural complex oxide phases with different ground states. Using ozone-assisted molecular beam epitaxy we synthesize such superlattices with sharp interfaces at the atomic layer limit. I will discuss two examples where the interfaces lead to novel electronic properties that do not exist in the bulk constituent phases: asymmetric ferroelectricity in three-component superlattices of titanate phases, and modified electronic and magnetic properties in ordered pseudo alloys of mixed-valent manganites.
