Local biphonons in anharmonic crystals with defects
Description
The spectrum of binary bound phonon oscillations-biphonons in quasimolecular crystals with defects is investigated. Defects-isotopic substitution impurities and vacancies are considered. Derivation of dispersion equation determining the spectrum of biphonon oscillations localized in the vicinity of defects is presented. The numerical solution results giving general idea on the behaviour of terms of local biphonon oscillations in case of changes in determining parameters are presented
