Subject: Stoichiometry Control of Emergent Phenomena at Complex Oxide Interfaces

Complex oxides with ABO3 perovskite structure have been of scientific nterests for a long time due to their ability to display a wide-range of phenomena. Recent advances in thin film growth approaches have enabled the growth of this material class in thin film and heterostructure forms with structural quality, which has now become similar to that of the conventional semiconductors. However the grand challenge in the field is to obtain these materials with the high level of stoichiometric and defect control. In this talk, we will present our group’s effort to address these challenges and to utilize stoichiometry defects as a new degree of freedom to control material’s physical phenomena using the hybrid molecular beam epitaxy (MBE) approach with the focus to understand and control novel electronic and magnetic ground states in defect-managed oxide thin films and heterostructures.
