Molecular Engineering of Nanocrystal Surfaces

Principal Investigator William Tisdale


A salient feature of colloidal QD materials is the presence of organic ligands coating each nanocrystal facet. By rationally tuning the surface chemistry, we can control the rate and mechanism of energy transport within QD ensembles. For instance, these ligands determine whether QD excited states move as free charges or as excitons, and they likely play a central role in regulating heat transport.
