Abstract
Photo- and thermo-structural changes occuring in vacuum-deposited amor phous chalcogenide films prepared by different methods have been inves tigated using Raman scattering. The changes in the Raman spectra of co nventionally prepared amorphous As2S3 films after: light treatment are interpreted in terms of rearrangement of bonding configurations of mo lecular species that exist just after evaporation. As the evaporation temperature or deposition rate is increased, heat or light treatment i nduces the formation of microcrystallites. The reversible photo-induce d changes in well-annealed films involve a vanishingly small change in bonding statistics. The most significant photostructural change occur s in the medium-range order.
