Pseudospin-phonon pretransitional dynamics in lead halide hybrid perovskites
B. Hehlen, P. Bourges, B. Rufflé +9
The low frequency lattice vibrations and relaxations are investigated in single crystals of the four 3D hybrid organolead perovskites, MAPbBr, FAPbBr, MAPbI, and -FA…

Micro-Brillouin spectroscopy mapping of the residual density field induced by Vickers indentation in a soda-lime silicate glass
H. Tran, S. Clément, R. Vialla +2
High-resolution Brillouin scattering is used to achieve 3-dimensional maps of the longitudinal acoustic mode frequency shift in soda-lime silicate glasses subject to Vickers indent…

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…
