Phonon-Induced Thermal Propertiesses thermal expansion. All these are integral contributions of the phonon spectrum; only at low temperatures, where part of the spectrum can be frozen-out, do they become partially spectrum selective. Thermal conductivity is determined by various mechanisms of phonon scattering.

Interaction of Light with Solids function of the frequency of the electromagnetic radiation: the complex dielectric constant. The dielectric constant describes the ability of a solid to screen an electric field – with electronic and ionic contributions – and is one of the most important material parameters. This function is closel

Photon–Free-Electron Interactionregion between the absorption edge and the Reststrahlen wavelength. In a driving external field, the ensemble of free electrons (or, at higher frequency, of valence-electrons) oscillates with respect to the ion cores on the whole, leading to a plasma resonance absorption. The plasmon dispersion has
