This event is part of the Biophysics/Condensed Matter Seminar Series.

Abstract: In this talk I will outline some recent experiments using very broadband (0.3 – 30 THz) pulses of far-infrared light called THz pulses to probe femtosecond and picosecond charge carrier dynamics and conduction mechanisms in materials such as bulk and nanocrystalline semiconductors, revealing the influence of disorder and confinement. I will also discuss our recent work on dynamic photonic components where we use an optical beam of light to control the propagation of a THz pulse inside a silicon chip.
