Abstract
We report a room-temperature study of the photoluminescence observed from a high-quality, molecular-beam-epitaxy grown GaAs-(AlGa)As multiple-quantum-well structure. The spectrum is dominated by free-exciton emission. This assignment is inferred by the use of photoluminescence excitation spectroscopy.Keywords
