Lattice dynamics of a monoclinic CsH₂PO₄ crystal
The phonon dispersion relations in a CsH₂PO₄ crystal in a paraelectric phase by means of a rigid molecular-ion model are calculated. The phonon spectra in the quasi-harmonic approximation at various values of temperature and hydrostatic pressure are obtained. The condensation of Au external phonon...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The phonon dispersion relations in a CsH₂PO₄ crystal in a paraelectric
phase by means of a rigid molecular-ion model are calculated. The phonon
spectra in the quasi-harmonic approximation at various values of temperature and hydrostatic pressure are obtained. The condensation of Au external phonon branch in the centre and at the boundary of the Brillouin zone
is obtained. |
