Network vs Molecular Structural Characteristics of Ge-Doped Arsenic Sulfide Glasses: A Combined Neutron/X-ray Diffraction, Extended X-ray Absorption Fine Structure, and Raman Spectroscopic Study

“…28,33 Compositional tie lines along the joins GeS 2 -As 2 S 3 and Ge 2 S 3 -As 2 S 3 and those along constant As:Ge ratios of 2:1, 1:1, and 1:2.5 represent ternary compositions in this system whose structures at the short and intermediate range have been studied previously by us and others using diffraction and spectroscopic techniques. 23,[25][26][27][28][29][30][31] compounds and proved to be adequate without further refinement. It is important to note that the Debye-Waller factor and the coordination number are correlated quantities in EXAFS data analysis and the quality of the fit can be kept unchanged by varying both the quantities simultaneously over a limited range.…”

“…A number of previous studies have investigated the compositional evolution of the length scale of intermediate-range order in ternary Ge-As-S glasses along the join GeS 2 -As 2 S 3 in a phenomenological fashion using Raman spectroscopy. [25][26][27] These studies have used the Ioffe-Regel criterion to relate the position of the Boson peak in the Raman spectra to a length scale of intermediate-range order that increased with increasing GeS 2 content and ranged from a few angstrom to 20 Å in GeS 2 -As 2 S 3 glasses. On the other hand, a recent Raman spectroscopic study of ternary (Ge 2 S 3 ) x (As 2 S 3 ) 1-x glasses has indicated possible "nanoscale phase separation" of small concentrations of As 4 S 4 and As 4 S 3 molecular units at low S deficiency and of ethane-like Ge 2 (S 1/2 ) 6 and distorted rock-saltlike GeS structural units at high S deficiency from the heteropolar-bonded GeS 2 -As 2 S 3 network.…”

XPS study of photo- and thermally-induced changes in amorphous Ge As40−S60

“…Due to the sulphur deficit, however, two types of structural units are also supposed to take part in the glass matrix-GeSlike [10] and ethane-like Ge 2 (S 1/2 ) 6 units [11]. Taking into account our Raman scattering investigation [12,13] and the spectra in Ref. [10], we suppose the prevalence of the ethane-like units over the GeS species.…”

Raman and DSC studies of fragility in tellurium‐zinc oxide glass formers

“…Recent works of chalcogenide [21] and tellurite [8] glass formers have shown that the systematic recording of the BP can be successfully used for the study of the glass transition and for the determination of critical points in the region of the glass transition.…”
