Phonon spectra of Cu₆PS₅Br superionic ferroelastic: experimental and theoretical studies
The anomalous temperature behavior of the Raman scattering bands at superionic phase transition of Cu₆PS₅Br is revealed. Using density functional perturbation theory within local density approximation, ab initio long-wavelength phonons have been obtained for high-symmetry cubic structure. In the cal...
