Image Nonequilibrium Charge Transport in Hybrid Perovskite Materials

​

Picture1.png

The simultaneously high spatial and temporal resolutions provide detailed understanding of the transport of  nonequilibrium states. 

 

We  investigate how unique properties of hybrid organic-inorganic metal halide perovskites lead to long-range transport of non-equilibrium hot charge carriers.

Control Coherent Exciton Transport

We evaluate exciton transport in the intermediate coupling regime in molecular aggregates, perovskite quantum dot self-assemblies, and photosynthetic antennas.

 

We exploit delocalized excitons in the intermediate coupling regime to facilitate long-range transport and to achieve robustness against defects in energy transfer networks

Heterostructures integrating 2D semiconductors offer new opportunities in developing new functionalities that are not available in bulk materials

 

We employ ultrafast microscopy to investigate energy transfer, charge transfer, and many-body exciton interactions at 2D interfaces. 

Leverage Strong Light-Matter Interactions

Exciton polaritons—hybrid exciton-photon quasi-particles—provide an exciting platform to design new optoelectronic functionalities. 

 

Here we  leverage strong light-matter interaction to overcome disorder and achieve long-range coherent transport
