Description
The aim of this project is to spatiotemporally study microscopic charge transport and dynamics in nanocrystal-based optoelectronics systems. Energy transport across nanoscale interfaces is fundamental to the physical chemistry and functionality of energy conversion applications. While advanced spectroscopic methods grant an understanding of excited-state dynamics in isolated materials, many physical questions about the microscopic nature of transport in optoelectronics devices remain underexplored. To address this area, one needs a probe of local charge transport with sub-nanosecond time resolution and sub-micron spatial resolution in a material with realistic device conditions. Our approach is to do pump-probe microscopy and fabricate nanocrystal-based optoelectronics. These studies will reveal microscopic structure–property relationships that connect nanoscale carrier dynamics to macro-scale energy conversion. The student will help to interface a pulsed white-light laser and spectrometer into an existing pump-probe microscopy setup, perform sample fabrication by lithography and self-assembly, and perform spectroscopy experiments to spatiotemporally measure the charge transport characteristics of advanced materials such as nanocrystal-based systems of interest. The student would be advised by Dr. James Utterback, a CNRS Chargé de Recherche at the Institut des NanoSciences de Paris (Sorbonne Université).
