Controlled Assembly of Quantum Dot Heterostructures

Abstract

The primary goals of this project were to learn how to control nanocrystal surface chemistry and to selectively functionalize semiconductor nanocrystals. This research was motivated by opportunities to incorporate semiconductor nanocrystals into various devices such as solar cells, solid-state lighting, photodetectors, field-effect transistors, and data storage systems. Unfortunately, current approaches to construct macroscale assemblies from nanocrystal building blocks produce materials with poor transport properties and ill-defined structure. In response, our research group has sought a long-term goal of developing new strategies for coupling colloidal nanocrystal building blocks through molecular linkers that can facilitate the efficient transport of charge carriers across the particle-particle interface and provide long-range order to the resulting assembly.
