(765a) Disorder, Nonequilibrium Transport, and the Origin of Deep Traps in Quantum Dot Solids

Using a combination of ultrafast spectroscopy, time-resolved optical microscopy, and kinetic Monte Carlo simulation, I will illustrate the effects of structural and energetic disorder on charge and exciton transport in colloidal quantum dot solids. In particular, I will show how analysis of early-time nonequilibrium transport phenomena can yield especially useful insight into fundamental charge and exciton transport processes. Additionally, I will present experimental evidence pointing to an unexpected origin of deep electronic traps in PbS nanocrystal solids.
