Energy Transport in Nanomaterials
Professor Mark Siemens' research interests lie in the use of ultra-fast lasers to understand transport of fundamental energy carriers in and near nanostructures.
Using laser pulses as short as a few quadrillionths of a second allows for spectroscopic measurement of electron, hole and phonon transport at their fundamental time scales. His work studies these processes in a variety of nanoscale systems, such as quantum-confined semiconductor systems and metal-on-insulator nanowires. These energy transfer processes are relevant to heat-sinking of nanocircuits and solar energy conversion.
