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…
A comprehensive model of the optical spectra of carbon nanotubes on substrate by polarized microscopy
Léonard Monniello, Huy-Nam Tran, Rémy Vialla +4
Polarized optical microscopy and spectroscopy are progressively becoming key methods for the high-throughput characterization of individual carbon nanotubes (CNTs) and other one-di…
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…
Anharmonic vs. relaxational sound damping in glasses: I. Brillouin scattering from densified silica
E. Rat, M. Foret, G. Massiera +4
This series discusses the origin of sound damping and dispersion in glasses. In particular, we address the relative importance of anharmonicity versus thermally activated relaxatio…
