Study vibrational and structural properties of Cu3SeTe by raman spectroscopy and XRD

The compounds Cu 3 SeTe were synthesized, the crystal structure and atomic dynamics were studied. As a result of X-ray diffraction studies, it was determined that the crystal structure of this compound corresponds to the cubic symmetry of the space group P-43 m. The studies of atomic dynamics were carried out by the method of Raman spectroscopy in the frequency range [Formula: see text]–800 cm[Formula: see text]. It was found that the Raman modes obtained at frequencies [Formula: see text], 91.47, 119.83, 139.51, 208.18 and 266.41 cm[Formula: see text] correspond to vibrations of metal–chalcogen and chalcogen–chalcogen bonds.
