Abstract

The i.r., Raman and depolarization spectra of the amorphous pseudo-binary alloy systems (GeS₂)_1-χ(As₂S₃)_χ and (GeSe₂)_1-χ(As₂Se₃)_χ are reported here. In contrast to the one-mode behavior that is anticipated on the basis of the mass ratio of the alloy atoms (Ge/As), two bond-stretching modes are observed in both the i.r. and Raman spectra. This new type of phonon behavior is interpreted in terms of differences in the local coordination via a chemical bonding model.
