Resonance Raman Scattering in [111]-Oriented CdTe/CdMnTe Superlattices
Cd1-xMnxTe alloys can be grown in zinc-blende structure up to a composition of х~0.7. The band gap of these crystals can be continuously tuned increasing the Mn composition.1 The difference between the band gaps ...

Magneto-Optics of [111] GaAs/GaAlAs Quantum Wells
The electronic and optical properties of GaAs/GaAlAs quantum wells (QWs) have been profusely studied in the last twenty years, since its concept was introduced by Esaki and Tsu[l]. Their optical properties are...

Inelastic Light Scattering by Free Electrons in GaAs Quantum Wires
We review recent inelastic light scattering studies of elementary excitations of the one-dimensional (1D) electron gas in the quantum limit, when only one or two 1D subbands are occupied by electrons. The ligh...

Hot Exciton Luminescence in Quantum Wells as a Spectroscopic Tool
Hot carrier effects are the subject of much interest in the study of transport properties in semiconductor heterostructures because of their importance in device reliability. The present work is devoted to som...

Double Raman Resonances in Semiconductor Multiquantum Wells Induced by High Magnetic Fields
Raman resonance profiles have been measured in GaAs/AlAs multiple-quantum wells (MQW) under magnetic fields up to 20T both for (100) and (111) crystal orientations. The intensity of the resonance increases by ...
