## Abstract We present a room temperature photoreflectance (PR) investigation of GaAsSb/GaAs/AlGaAs quantum well (QW) structures grown on GaAs substrates by molecular beam epitaxy. We encounter strong low energy interference oscillations (LEIO), which tend to obscure any PR signals arising from the
