Research Interest

Science and technology at nanoscale have numerous opportunities for fundamental research as well as new applications. Quantum dots (nanocrystals), nanowires, and nanorods are among the most important building blocks of nano-photonic devices. Therefore, the understanding of underlying fundamental physical phenomena in such structures is very important for future progress. We are interested in fundamental properties of wide bad gap nanostructured materials, including those with type-II band alignment, with potential application in photo-detection, quantum information, and biomedical field.
