Transition metal oxides exhibit rich phase diagrams and exotic physical properties as a result of strong correlations between multiple degrees of freedoms. The recent advance of thin film growth techniques allows the synthesis of high-quality epitaxial oxide heterostructures with precise thickness, structure and composition controls. In this presentation, I will first discuss the emerging opportunities to construct interface-based nonvolatile resistive switching memory and field effect transistor. Electrostatic bias can manipulate the configuration of charged defects, and tune the Kondo effect and two-dimensional insulator-to-metal transition. I will also discuss the emergence of exchange bias and reentrant spin glass state at interfaces between ferromagnetic and antiferromagnetic oxides. Finally, I will introduce our preliminary result of superconductivity in orthorhombic-structured Ti2O3 films. As a whole, the basic principles of materials physics behind these emergent physical properties of oxide interfaces might provide opportunities of future technology breakthroughs. |
