(62b) NSEF Young Investigator Award - Disorder, Nonequilibrium Transport, and the Critical Role of Size Dispersity in Colloidal Semiconductor Nanomaterials

Colloidal semiconductor nanocrystals are a promising platform for next-generation solution-processable photovoltaic, lighting, and sensing technologies. Using a combination of ultrafast spectroscopy, time-resolved optical microscopy, and kinetic Monte Carlo simulation, I will show how analysis of early-time nonequilibrium charge transport phenomena can yield especially detailed insight into the performance of electrically conductive nanocrystal solids. In particular, I will illustrate the effect of structural and energetic disorder, the role of dimensionality and surface chemistry, and the self-organization of these nanomaterials into ordered superstructures.
