We study oxide materials science with emphasis on elucidating structure-property relations and exploratory solid state devices. Problems of interest center around controlled synthesis of oxide thin films; investigating effects of microstructure, interfaces and point defects in determining functional properties involving electronic and ionic transport.

Some on-going projects include:

• Studies on the metal-insulator transition in rutile oxides (such as VO2) and electron devices
• Novel solid-state energy materials synthesis and devices thereof
• High temperature ionic and electronic transport in thin film oxide-ion conductors; instrumentation and technique development
• Ultra-thin oxide synthesis, electric field effects and passivity breakdown
