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.
