Imaging of semiconductor surface impurities by femtosecond near-field photoconductivity



W Schade, D L. Osborn, J Preusser, S R. Leone


Femtosecond pump-probe near-field photoconductivity is used to investigate the time response of surface impurities on a GaAsP diffusion type photodiode. At the defects, recovery times of less than 100 fs are obtained.
