Research

Ultrafast dynamics in honeycomb Mott insulator

We combine optical transient spectroscopy and time-resolved RIXS (tr-RIXS) spectroscopy to study 5-d orbital dynamics in the honeycomb Mott insulator α-Li2IrO3.

Ultrafast Carrier Injection Dynamics in Perovskite

We mimic transient carrier injection via ultrafast laser excitation and take advantage of sub-picosecond time resolution to explore carriers excitation dynamics in perovskite WBGOs.
