Excited States Electronic Coupling, and Charge Transfer Properties of Chalcogenide-capped Semiconductor Nanocrystals
Abstract
The goal of this research is to understand how chalcogenide surface-capping ligands (e.g., S2-, Se2-, Te2-) impact the excited state dynamics, electronic coupling, and ultimately charge transfer properties of colloidal semiconductor quantum dots. The work aims to learn how to control electron and hole relaxation and trapping dynamics using molecules that bind to surface trap sites. This work will elucidate some of the critical aspects of quantum dots capped with chalcogenide ligands and will inform the design of devices that optimally utilize the electronic properties of these materials.
