Vibrational Spectra of Crystals and Superlattices Electron-Phonon Interaction,e needed in Chap. 8 which is devoted to light scattering. Nevertheless, application of group theory to the classification of vibrational spectra of bulk crystals and superlattices illustrates the power of these methods. Their use permits one, without recourse to concrete calculations, to establish t

Interband Optical Transitions,e form of Bloch solutions. We discriminate between optical superlattices and short-period regular heterostructures. In an optical superlattice, adjacent layers have different dielectrical constants. Apart from this, the layers are assumed to be thick enough to be able to neglect electron and hole qu

Electron Spectrum in Crystals, Quantum Wells and Superlattices,se in the theory of semiconductors and of materials where the carrier concentration is usually much lower than the number of lattice atoms, and therefore the electrons and holes cluster near the extrema.
