Ultrafast Spectroscopy

Principal Investigator William Tisdale


Excited state electron dynamics are central to the operation of the most promising futuristic solar cells. Important dynamic events typically occur on picosecond or sub-picosecond time scales – faster than the capabilities of present-day electronics. To probe such processes, the use of femtosecond (1 fs = 10-15 s) pulsed lasers is required. Currently, we are using femtosecond second harmonic generation (SHG) to investigate excited state dynamics at organic and inorganic nanostructured materials interfaces. For an example of the capabilities of this approach.
