Chemical Engineering Seminar

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