About

Our research centers around the physics and applications of quantum materials, with a particular emphasis on the strongly correlated oxides. The research work spans from the synthesis of novel materials and heterostructures, especially utilizing a “materials-by-design” approach to discover material systems (thin films, heterostructures, superlattices, or interfaces) with properties superior to any known, to the studying of the physics of these new emerging properties, and to the development of functional devices exploiting the emergent properties.
