Current Activity : Growth of heterostructures using lithography, wet chemistry and study of their quantum phenomena at interfaces for potential devices. ‘ Quantum phenomena at interfaces' is a very active subject of research and has potential applications in memory storage, sensors, amplifiers and resonators. It also has tremendous potential for metrology and developing standards. Our group is looking into aspects of characterizing these phenomena and device fabrication using lithographic techniques.
