Low-frequency vibrational spectroscopy of glasses
Benoit Rufflé, Marie Foret, Bernard Hehlen
Atomic vibrations in perfect, slightly defective or mixed crystals are to a large extent well understood since many decades. Theoretical descriptions are thus in excellent agreemen…
Direct evidence of weakly dispersed and strongly anharmonic optical phonons in hybrid perovskites
A. C. Ferreira, S. Paofai, A. Létoublon +8
Hybrid organolead perovskites (HOP) have started to establish themselves in the field of photovoltaics, mainly due to their great optoelectronic properties and steadily improving s…
Atomic Vibrations in Glasses
B. Hehlen, B. Rufflé
In glasses, atomic disorder combined with atomic connectivity makes understanding of the nature of the vibrations much more complex than in crystals or molecules. With a simple mod…
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…
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…
