Probing Medium Range Order In Chalcogenide Glasses By Neutron Scattering And Optical Spectroscopy Gese2 Sise2 P50 Se50 Sio2 PDF Download

The use of neutron diffraction, neutron inelastic scattering, and optical spectroscopy to probe the nature of the medium-range order (MRO) in amorphous materials is discussed with reference to chalcogenides of GeSe2, SiSe2, and also P50Se50, and SiO2 glasses. While none of these probes provides a unique determination of the MRO, the use of information obtained from the three techniques, supplemented by numerical calculations based on specific structural models, can provide a picture of the essential elements of glass structure. 5 refs., 4 figs.
