Abstract
At the nanoscale, energy carrier transport must navigate length scales intrinsic to material defects. How do heterogeneous environments and interfaces impact transport properties? How can we access information about energy carriers that traditionally do not have clear spectroscopic signals? In this presentation I will describe ultrafast optical measurements and theoretical modeling of the behavior of various types of energy carriers at the nanoscale, including band-edge and trapped charge-carrier dynamics in colloidal nanocrystals, heat transport in nanocrystal films, and ion transport in solution.
