Abstract
Direct studies of the transport of photogenerated electron-hole pairs in semiconductor nanostructures require both high spatial and temporal resolution. Near-field scanning optical microscopy (NSOM), offering subwave-length spatial resolution in the 100-nm range in combination with time-resolved detection schemes is a particularly promising technique for such experiments. Here we report on the first time-resolved near-field spectroscopic investigation of the carrier dynamics in single gallium arsenide (GaAs)/(AlGa)As sidewall quantum wires.
