Theory of multiphonon absorption in the wings of internal vibrational modes of impurities in ionic crystals

Green's function methods are applied to obtain the multiphonon absorption coefficient in crystals containing impurities with internal vibrational modes. The results imply that the shape of the wing absorption from such modes is determined by the host lattice density of states, but with a fall-o...

Abstract Green's function methods are applied to obtain the multiphonon absorption coefficient in crystals containing impurities with internal vibrational modes. The results imply that the shape of the wing absorption from such modes is determined by the host lattice density of states, but with a fall-off rate determined by the range of the lattice-impurity interaction potential. Green Funktions-Methoden werden dazu benutzt, den Multiphonon-Absorptiooskoeffizienten von Kristallen zu berechnen, welche Störstellen mit internen Vibrationsschwingungen enthalten. Den Resultaten zufolge wird die Form der Absroptionsseiten bande solcher Moden durch die Zustandsdichte des Wirtskristalls bestimmt, deren Abfall-Rate jedoch durch die Reichweite des Gitter-Störstellen - Wechselwirkungspotentials.
