Scaling the Temperature-dependent Boson Peak of Vitreous Silica with the high-frequency Bulk Modulus derived from Brillouin Scattering Data
B. Rufflé, S. Ayrinhac, E. Courtens +4
The position and strength of the boson peak in silica glass vary considerably with temperature . Such variations cannot be explained solely with changes in the Debye energy. New…
Hyper-Raman scattering analysis of the vibrations in vitreous boron oxide
G. Simon, B. Hehlen, R. Vacher +1
Hyper-Raman scattering has been measured on vitreous boron oxide, BO. This spectroscopy, complemented with Raman scattering and infrared absorption, reveals the full se…
The Boson Peak and its Relation with Acoustic Attenuation in Glasses
B. Rufflé, D. A. Parshin, E. Courtens +1
Experimental results on the density of states and on the acoustic modes of glasses in the THz region are compared to the predictions of two categories of models. A recent one, sole…
Hyper-Raman scattering from vitreous boron oxide: coherent enhancement of the boson peak
G. Simon, B. Hehlen, E. Courtens +2
Hyper-Raman scattering spectra of vitreous BO are reported and compared to Raman scattering results. The main features are indexed in terms of vibrations of structural unit…
Acoustic damping in LiO-2BO glass observed by inelastic x-ray and optical Brillouin scattering
B. Rufflé, G. Guimbretière, E. Courtens +2
The dynamic structure factor of lithium-diborate glass has been measured at several values of the momentum transfer using high resolution inelastic x-ray scattering. Much atten…
Anharmonic vs. relaxational sound damping in glasses: II. Vitreous silica
R. Vacher, E. Courtens, M. Foret
The temperature dependence of the frequency dispersion in the sound velocity and damping of vitreous silica is reanalyzed. Thermally activated relaxation accounts for the sound att…
