Assistant Professor Department of Electrical and Electronic Engineering   Research Group

My research interests are focused on electronics, optoelectronics, and physical property characterizations based on emerging two-dimensional materials. Dr. Chen has done pioneering research on thin-film black phosphorus transistors, transition-metal dichalcogenides (TMDs) and graphene quantum capacitors. In recent years, he has published over 40 pioneer-reviewed research papers on Nature communications, Light: Science & Applications, Science Advances, Advanced Materials, ACS Nano, Nano Letters etc..
