"We report on the infrared spectra of the antisymmetric stretching vibration of Oi in Si-rich Si1xGex alloys. The shift of its frequency is obtained as a function of the germanium content x below 0:5. We present a decomposition of the low-temperature spectra using GaussLorentz profiles. A low-lying broad band is found for x \u017A 0:08, and assigned tentatively to the vibrations of Si2O units with the nearest sites occupied by several Ge atoms. We compare our experimental findings with results of a recent ab initio study of the phonon modes." . "479698" . "[106D5EC88C3F]" . "Physica B" . . . .
