Abstract
Piezoreflectance characterization has been applied for GaAs/AlAs multiple quantum wells. The room-temperature spectra have revealed sharp reflectance features due to interband transitions in the quantum wells, as well as in the AlAs barrier. The spectral features are described in terms of the strain-induced interband energy shifts.
