AbstractEmploying temperature dependent photoconductivity, photoluminescence and photoreflectivity measurements, we have analyzed a GaAs-AlAs multiple quantum well. The above optical techniques clearly resolve the fundamental inter-subband transitions, including heavy hole-light hole splittings. At T < 60K an anomalously high photoconductivity was discovered below the direct inter-subband transitions and is attributed tentatively to the presence of extrinsic interface states within the bandgap. For T > l00K the fundamental indirect transition was discovered and associated with LO (L) - phonon absorption.

Progressive Deterioration

Maintaining crystal quality during the growth of very thick multiple-quantum-wells is challenging due to the progressive deterioration in thick low-temperature barriers. The insertion of several high-temperature crystallinity restoring (CR) layers...
