Peculiarities of Raman scattering in nanometric Cu_6PS_5Br superionic conductors
Cu_6PS_5Br superionic conductors were obtained in nanocrystalline state by ball milling. Phonon spectra of micro- and nanopowders are studied by Raman spectroscopy. Due to the crystallite size reduction the essential low-frequency shifts of Raman scattering bands, their broadening and intensity decrease are observed. The specific features of Raman spectra in nanometric superionic conductors are explained predominantly by surface phonon modes.
