title = "Vibrational lifetimes and isotope effects of interstitial oxygen in silicon and germanium",
abstract = "Time-resolved, transient bleaching spectroscopy was used to measure the lifetimes of the asymmetric stretch mode of interstitial isotopes 16O and 17O in Si. It was found that the 17O lies in the highest phonon density resulting in the shortest lifetime, by a calculation of the three-phonon density of states. It was also found that the lifetime of Ge is ten times longer than Si. According to the activity of phonon combinations, the interaction between the local modes and the lattice vibrations is discussed.",
