Abstract:

2D metal halide perovskite semiconductors have shown intriguing properties for optoelectronic applications. Both strongly bound excitons with binding energy up to a few hundreds of meV and polaronic characters have been observed in 2D perovskites but how the interplay between them redefines the nature of exciton polarons and their excited-state dynamics still remains largely unexplored. In this talk, we discuss our recent experimental findings about the exciton polarons in 2D metal halide perovskites and their significant impact on the light emission and charge transfer properties.

Biography:

Haiming Zhu got his B.S degree on Chemical Physics in University of Science and Technology of China in 2008 and PhD in Physical Chemistry from Emory University in 2014. Afterwards, he worked as a postdoc scientist in Columbia University in the City of New York. He joined Department of Chemistry in Zhejiang University as a tenure-track professor since July 2016. His research has mainly focused on using ultrafast laser spectroscopy to investigate excited state dynamics in low dimensional materials and at interface.
