In nanostructured materials, the short length and time scales over which energy moves can manifest in transport behavior that deviates from classical constitutive laws. Using a combination of ultrafast laser spectroscopy, time-resolved optical microscopy, and kinetic Monte Carlo simulation, I will show how these effects manifest in assemblies of colloidal quantum dots (QD) and atomically thin 2D semiconductors, which are promising components of next-generation photovoltaic and lighting technologies. In particular, I will demonstrate the effect of structural and energetic disorder, the role of dimensionality and surface chemistry, and the self-organization of these nanomaterials into ordered superstructures.
