The low frequency lattice vibrations and relaxations are investigated in single crystals of the four 3D hybrid organolead perovskites, MAPbBr$_3$, FAPbBr$_3$, MAPbI$_3$, and $\alpha$-FAPbI$_3$, at the Brillouin zone center using Raman and Brillouin s

Brillouin scattering and ultrasonic measurements of the elastic constants of CuGeO3

Autor: G. Dhalenne, M. Saint-Paul, C Ecolivet, A. Revcolevschi

Publikováno v: Journal of Physics: Condensed Matter. 11:4157-4162

The sound velocities for longitudinal and transverse waves in single-crystalline CuGeO3 have been measured using ultrasonic pulse-echo and Brillouin scattering techniques. The nine independent elastic constants have been determined. The elastic prope
