Acoustic Anomalies and the Critical Slowing-Down Behavior of MAPbCl<sub>3</sub> Single Crystals Studied by Brillouin Light Scattering

Inelastic light scattering spectra of organic–inorganic halide perovskite MAPbCl<sub>3</sub> single crystals were investigated by using Brillouin spectroscopy. Sound velocities and acoustic absorption coefficients of longitudinal and transverse acoustic modes propagating along the cubic...
