ABSTRACT
Investigates the sensitivity of resonant and photoluminescent excitation measurements to exciton localization effects in gallium arsenide (GaAs)/aluminum GaAs quantum wells. Evidence on effective submonolayer well width fluctuations; Predominance of localized excitons; Information on the free diffusion of delocalized excitons to differing regions.
