Raman spectra and structure of GeAsS glasses in the S-rich region
The Raman spectra of GexAsySz glasses have been studied in the ternary composition region of GeS2-As2-S. Dominant features of the obtained spectra were discussed and the structural units forming the disordered structural network of GexAsySz glasses were identified as: GeS4 tetrahedra, AsS3 pyramids, As-S-S-As bent chains and Sn (n = 2–4) chain segments. At high sulfur concentrations a part of the sulfur is dissolved in the structural network in the form of S8 molecules.
