Pressure-induced densification of vitreous silica: insight from elastic properties
Coralie Weigel, Marouane Mebarki, Sébastien Clément +3
\textit{In situ} high-pressure Brillouin light scattering experiments along loading-unloading paths are used to investigate the compressibility of vitreous silica. An accurate equa…
Vitreous silica distends in helium gas: acoustic vs. static compressibilities
Coralie Weigel, Alain Polian, Mathieu Kint +3
Sound velocities of vitreous silica are measured under He compression in the pressure range 0-6 GPa by Brillouin light scattering. It is found that the well-known anomalous maximum…
Acoustic damping and dispersion in vitreous germanium oxide
Guillaume Guimbretière, Benoît Rufflé, René Vacher
New Brillouin scattering measurements of velocity and attenuation of sound in the hypersonic regime are presented. The data are analyzed together with the literature results at son…
Eliminating the broadening by finite aperture in Brillouin spectroscopy
R. Vialla, B. Rufflé, G. Guimbretière +1
We present a new optical arrangement which allows to avoid the broadening by finite aperture in Brillouin spectroscopy. In this system, all the rays scattered at the same angle by…
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…
