Due to inclement weather conditions in early Feb, we have shifted the first Boston Area Excitonics Seminar to March 9th at 12 Oxford St, Division Room. Food will be served at 6:00 pm. Our speaker, Prof. Will Tisdale, will be presenting on “Excitoncs, Disorder, and Nonequilibrium Transport in Semiconductor Nanomaterials.” 

In semiconductor nanomaterials, spatial confinement and structural heterogeneity can present transport behavior that deviates markedly from the bulk phase. Using a combination of ultrafast spectroscopy, timeresolved optical microscopy, and kinetic Monte Carlo simulation, I will show how these effects manifest in assemblies of colloidal quantum dots (QD) and atomically thin two-dimensional semiconductors. As an area of emerging focus in my group, I will highlight some of the intriguing and counterintuitive aspects of exciton transport, annihilation, and interfacial transfer in 2D materials.
