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


UPQD 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.
