LIEN

Photon–Phonon Interactiondispersion is described by a phonon-polariton, which is observed in inelastic scattering processes. Brillouin scattering at acoustic phonons and Raman scattering at optical phonons provide direct information about the spectrum and symmetry of vibrations in a semiconductor.

Elasticity and Phononss equivalent to a harmonic oscillator which can be quantized as a phonon. Phonons are one of the most important quasiparticles in solids. They are responsible for all thermal properties and, when interacting with other quasiparticles, for the damping of their motion.

Band-to-Band Transitionstates extending beyond the band edge, usually as an Urbach tail which decreases exponentially with distance from the band edge. In quantum wells the two-dimensional joint density of states leads to a steplike increase of the absorption for increasing photon energy.

Hiatal-Hernia

Interaction of Light with Solids for electrons traveling in the periodic crystal potential. A complete bandgap for propagation along any direction can be created for three-dimensional periodicity; defects given by deviations from periodicity lead to localized states in such photonic crystals, similar to effects in the electronic c
