| From the Raman spectra performed at temperatures from 10 K to 295 K for Hg1-xFexS crystals containing up to a few percent of iron the phonon energies for selected high-symmetry points of the Brillouin zone have been determined. A very high ionicity of these mixed crystals has been found. The TO phonon frequency value for β-HgS at Γ point, equal to about 177 cm-1, suggested previously in the literature, has been confirmed. |
