Research Interest

My research mainly focuses on the study of photo-induced dynamics of photovoltaic and optoelectronic nanomaterials including semiconductor quantum dots, nanowires, perovskite materials; charaterization on crystal and electronic structures of nanomaterials.

Current Projects

- Photo-induced dynamics in perovskite quantum dots

- Investigation on the interface properties between perovskite and graphene

Former projects

*Ultrafast charge transfer in CdSe QDs sensitized ZnO nanostructures* (hyperlink)

*Charge carrier dynamics in organometallic halide perovskite materials* (hyperlink)
