Ultrafast photophysics of quantum materials (UPQM) group leads a unique research direction to understand ultrafast dynamics of next generation quantum materials and quantum devices. The research of UPQM group is to bridge the gap between fundamental photophysics and devices, and to develop next generation technologies to make contributions to society.


UPQM group research includes three areas:

  • Ultrafast carrier dynamics in situ devices: a) ultrafast photocurrent spectroscopy (U-PCS); b) ultrafast electroluminescence spectroscopy (U-ELS).
  • Next generation quantum devices: electrically-driven single-photon emitter (quantum dot LED), single-photon detector (infrared high-speed photodetector), solar cells, and thin film transistors.
  • Quantum materials synthesis and novel property characterization.
