Condensed Matter Experiment

Research

Prof. Li’s research unveils structure and property relationships of condensed matter at the atomic scale. Current interests are the molecular beam epitaxy (MBE) growth of Dirac materials (e.g., graphene, topological insulators, and Wey semimetals), Fe-based superconductors, and 2D transition metal dichalcogenides, and application of in situ low temperature scanning tunneling microscopy/spectroscopy (STM/S) and angle-resolved photoemission spectroscopy (ARPES) to gain new insights into these quantum phases of matter from the interplay of strain, proximity, correlations, and spin-orbit interactions. The research is currently supported by grants from NSF and DOE.

Biographical Sketch

Prof. Li received his BSc in Physics from Yunnan University, China in 1983, and MSc in the same field from Tongji University, China in 1987, and PhD in Solid State Physics from Arizona State University in 1995. He received a Fellowship from the Japan Society for the Promotion of Science to conduct research at the Institute for Materials Research, Tohoku University, Japan from 1995 to 1996, and held a staff research associate position at the University of California, Los Angeles from 1996 to 1999. He joined the Physics department at University of Wisconsin-Milwaukee as an Assistant Professor in 1999, and was promoted to full Professor in 2007. He joined the Department of Physics and Astronomy at West Virginia University as Robert L. Carroll Professor of Physics in 2016. Prof. Li received the E. W. Müller Outstanding Young Scientist Award from the International Field Emission Society (1996) and NSF CAREER Award (2001).
