Infrared Model Dielectric Functions

  • Mathias Schubert
Part of the Springer Tracts in Modern Physics book series (STMP, volume 209)


This chapter reviews a selection of dielectric function models progressed for lineshape analysis of (far) infrared ellipsometry data. Contributions to the dielectric function due to polar lattice vibrations (phonons), impurity (lowpolarity) vibration modes, and free-charge-carrier plasma excitations are discussed. A condensed derivation for the classical anisotropic magneto-optic free-charge-carrier contribution is given.
