Vibrational Lifetime of Interstitial Oxygen in Crystalline Silicon
The lifetime of the antisymmetric stretch mode of interstitial oxygen in crystalline Si is measured directly by time-resolved, transient bleaching spectroscopy to be T1 = 229 ± 16 ps at 10 K. The temperature dependence of the lifetime shows that the stretch mode decays into eight vibrational modes of 142 ± 20 cm. The low-temperature width of the FTIR (IR) absorption line due to the stretch mode...
متن کاملInterstitial charge states in boron-implanted silicon
It is becoming increasingly clear that simulation models of transient enhanced diffusion sTEDd in silicon need to incorporate interstitial charging effects accurately in order to adequately reproduce experimental data near the surface and near the underlying junction. However, in the case of boron TED, the relevant charge states and ionization levels of both boron and silicon interstitial atoms...
متن کاملInterstitial oxygen in germanium and silicon
The microscopic structure of interstitial oxygen in germanium and its associated dynamics are studied both experimentally and theoretically. The infrared absorption spectrum is calculated with a dynamical matrix model based on first-principles total-energy calculations describing the potential energy for the nuclear motions. Spectral features and isotope shifts are calculated and compared with ...
متن کاملFirst-principles calculations of interstitial boron in silicon
We perform first-principles total-energy calculations to identify the stable and metastable configurations of interstitial B in Si. We calculate formation energies and ionization levels for several equilibrium ionic configurations in different possible charge states. In all charge states the ground state consists of a B atom close to a substitutional site and a Si self-interstitial nearby. The ...
متن کاملVibrational lifetimes and isotope effects of interstitial oxygen in silicon and germanium.
Decay dynamics of local vibrational modes provides unique information about energy relaxation processes to solid-state phonon bath. In this Letter the lifetimes of the asymmetric stretch mode of interstitial 16O and 17O isotopes in Si are measured at 10 K directly by time-resolved, transient bleaching spectroscopy to be 11.5 and 4.5 ps, respectively. A calculation of the three-phonon density of...
