Circular polarization-resolved UV PAS

Welcome to LI research group!

        We are interested in:

  • Studies of charge/energy/spin dynamics, light-matter interactions, and novel photophysics in optical materials and devices (e.g., semiconductor quantum dots, 2D materials, metasurface, and related optoelectronic devices) using state-of-the-art ultrafast optical spectroscopies.
