“…The band at 480 cm −1 can be attributed to S−S stretching vibrations, as it was reported for the 475 cm −1 band of CuS films and nanoparticles [22,23]. The band at 373 cm −1 was not reported among the Raman bands of CuCl [29,30] and CuS. We suppose that the Raman data generally verify the formation of polymeric one-dimensional CuS as a part of the hybrid interpolymeric PVA-CuS compound.…”

PVA-CuS compound produced from hybrid interpolymeric polyvinyl alcohol (PVA)-CuCl2 complex through solid state sulfurization was investigated by means of X-ray diffraction, UV-Vis and Raman spectroscopy, and direct current measurements. It is claimed that CuS in this compound has one-dimensional structure. This result is achieved by using a precursor technique based on diffusion limitation at solid state synthesis, so that the structure of initial reagents is inherited by reaction products. The produced material is determined to possess metal-type conductivity and thermopower in the vicinity of room temperature. Keywords: hybrid interpolymeric complexes, polyvinyl alcohol, CuS, inorganic polymers, one-dimensional structures, electrical properties.

“…This resonance can be lifted by applying pressure. The TO phonon shifts up in frequency considerably faster than the LA + TA structure (because of the negative γ TA ), and at about 3 GPa the Fermi resonance has all but disappeared [46]: A nice Lorentzian peak appears at the frequency ω 0 . Similar effects can be produced by isotopic substitution since ω 0 shifts approximately like M Cl -1/2 , whereas the LA and TA frequencies shift like M Cu -1/2 [47].…”

We discuss the dependence of phonon frequencies on hydrostatic pressure for tetrahedrally bonded semiconductors, in particular the linear term represented by mode Grüneisen parameters. The relation between these parameters and the thermal expansion is also elucidated. Emphasis is placed on recent results that concern the zero-point renormalization of lattice parameters and its dependence on isotopic masses. The pressure dependence of transverse charges of ir-active phonons is also touched upon. We also discuss strong pressure and isotopic mass effects on phonon widths and line shapes that are occasionally observed for selected materials. Finally, we present recently observed effects of pressure on the luminescence of isotopically pure silicon which are strong enough to be easily detected in the 0 -1 bar range.
