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…
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…
