The dynamics of storage and recombination of electron-hole pairs in quantum-well-based light memory cells driven by high-frequency electric fields is investigated by spatially and time-resolved photoluminescence spectroscopy. In these cells, a laterally modulated potential is used to ionize and spatially separate photogenerated electron-hole pairs. The temporal and spatial dependence of the carrier dynamics depends not only on the modulated potential, but also on the transport properties of electrons and holes. © 2000 American Institute of Physics.
