Abstract

We have investigated the dynamics of the ambipolar transport of photogenerated electrons and holes induced by surface acoustic waves in GaAs quantum wires by using photoluminescence measurements with spatial and temporal resolutions. This technique allows us to trace the trajectory of charge packages in real time and to access the dynamics of radiative trapping centers. We identify two different kinds of trapping defects, which capture preferentially either holes or electrons
