Paper Abstract

Presented here is a brief review of the dominant features of quantum wells and superlattices that are seen in light scattering spectra, and how these can provide quantitative and qualitative information about the structures. These features include effects of acoustic phonon zone folding, optical phonon quantum levels, peak intensity variation due to interface disorder, scattering resonances at quantized electronic gaps, and peaks due to transitions between electronic levels in modulation doped structures. Quantitative information obtained includes layer periods, well widths, and electronic level energies. Some conclusions can also be made concerning structural disorder, interface broadening, and the amount of strain in lattice mismatched systems.
