My research is focused on investigating single crystalline thin films and heterostructures of complex transition-metal oxides grown using the technique of oxide molecular beam epitaxy (MBE). My group has designed and constructed a custom oxide MBE system that is capable of growing state-of-the-art films and heterostructures on oxide substrates and semiconductors. The main objectives of my research are to: (1) elucidate fundamental physical principles by which novel material behavior or functionality can be realized in nanoscale oxide heterostructures; (2) develop prototypical devices based on oxide heterostructures for use in information processing, sensing or energy harvesting.
