In this thesis, we investigate the ultrafast photocurrent response of semiconductor nanowires to advance the development of ultrafast and small nanowire photo-switches. Using a THz-time domain photocurrent spectroscopy, the photocurrents in single nanowires are measured with a picosecond time resolution. Hereby, the mechanisms are identified and characterized which generate a photocurrent in a nanowire. The obtained findings contribute to a better understanding of the optoelectronic properties of semiconductor nanowires.
