Integrated Films of Transition Metal Oxides for Information Technology

Abstract: The recently developed ability to grow layers of transition metal oxides with the atomic precision by means of physical vapor deposition has led to discovery of many fascinating phenomena that cannot be easily realized in bulk materials and to integration of these oxides on semiconductors. In this talk I will review the recent progress in integrating ferroelectric films with Si and Ge, and their potential applications in electronics and nanophotonics. I will also talk about potential applications of perovskite oxide heterostructures. Heterostructures described in the talk were grown by molecular beam epitaxy (MBE), when possible, chemical routs were tested via atomic layer deposition (ALD). Design of the structures and analysis of the experimental results were aided by density functional theory (DFT).
