Abstract
In this work, the experimental evidence of exciton confinement in the GaAs barriers of InGaAs/GaAs multiple-quantum-well structures is reported. This has been achieved by an ad hoc devised luminescence self-absorption spectroscopy method, as well as by standard photoluminescence, performed at different temperatures, which present a spectral feature at energies higher than those of bulk GaAs. The confinement energy and the linewidth depend on the barrier width, in agreement with a simple quantum mechanical model. Higher index states of the barrier exciton are also observed. The data underscore the critical importance of the choice of the sample-structure parameters for the confinement to be detectable.
