Complex oxides with ABO3 perovskite structure have been of scientific interests 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 materials class in thin films and heterostructures form with an excellent 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 stoichiometry and defect control. In this talk, we will present our group’s effort to address these challenges using the hybrid molecular beam epitaxy (MBE) approach by combining the advantages of conventional MBE and metal-organic chemical vapor deposition with the focus to understand and control novel electronic and ferroic phenomena in defect-managed oxide thin films and heterostructures.
Bharat Jalan joined the faculty of the Department of Chemical Engineering and Materials Science at the University of Minnesota as an assistant professor. Prior to his joining in 2011, he received his bachelor in 2006 at the Indian Institute of Technology Madras and a Ph.D in 2011 in Materials at the University of California, Santa Barbara. His research is focused on the study of materials physics of complex oxide thin films and heterostructures. He is recipient of an AFOSR Young investigator award and the biennial International MBE Young Investigator Award. He has also been an active member of the materials science and physics community. He has co-organized several international and national meetings and workshops including MRS Electronic Material Conference (EMC), an invited co-organizer of a focus session on the topic of “Complex Oxide Interfaces and Heterostructures” at the APS March meeting in San Antonio-2015, in addition to co-organizing of a symposium at the American Ceramic Society (ACers) Electronic Materials and Applications (EMA) meetings (2015-2017) in Orlando, Workshop on Oxide Electronics (2017)” in Chicago, and an international oxide meeting to be held in Rome, Italy in July 2017. He has also served as an invited member of the MRS task force for the strategic planning for the National Nanotechnology Initiative submitted to the White House (NNI – 2010).
