Our recent research scope focuses more on the study of 2D materials such as graphene, topological insulators, and 2D transition metal dichalcogenides(TMDs).  We grow these ultrathin films by molecular beam epitaxy (MBE), pulsed laser deposition (PLD) and sputter.   

​

We carry out fundamental analysis of the 2D materials including atomic structure study by STM, soft x-ray absorption spectroscopy study by using synchrotron radiation facilities, as well as transport magneto-transport studies on these films.

Based on these 2D materials, we also prepare FET and spin pumping devices for spintronic and valleytronic applications. For energy applications, we also carry out research on solar cell photodetector devices based on perovskite and TIs.
