Nano-electronic Functional Materials Laboratory
Complex Oxide Physics Laboratory

The research of our group covers a broad range of heteroepitaxy of complex oxides and their characterizations. We "design" and actually "build" various thin film heterostructures of metal oxides, expecting something surprising. Whenever a correlated oxide, such as transition metal oxides, forms an interface with a different oxide material, the strong electronic correlation at the interface results in subtle effects on the atomic structures as well as the change of physical properties. Such subtle effects can lead to a completely new ground state, not present in typical semiconductors. Our interest also includes the device applications of epitaxial oxide thin film heterostructures, for example, ferroelectric tunnel junctions, memristors, and quantum transistors based on 2-dimensional electron/ hole gas at the interface.
