Atomic structure of As2S3-Ag chalcogenide glasses
Original language description
(As0.4S0.6)100-Ag-x(x) glasses have been studied with high-energy x-ray diffraction, neutron diffraction and extended x-ray absorption spectroscopy at As and Ag K-edges. Experiments were modelled with the reverse Monte Carlo simulation method. Analysis of the partial pair correlation functions and coordination numbers extracted from the model atomic configurations revealed that silver preferentially bonds to sulfur in the As2S3-Ag ternary glasses, which results in the formation of homoatomic As-As bonds. Upon the addition of Ag, a small proportion of Ag-As bonds are formed in all three ternary compositions, the direct Ag-Ag bonds appear only in the glass with the highest Ag content. Similar to the g-As2S3 binary, the mean coordination number of arsenicis close to three, and that of sulfur is close to two, in the As2S3-Ag ternary glasses. The first sharp diffraction peak on the total structure factors of As2S3 binary and (As0.4S0.6)(100-x)Ag-x ternary glasses is related to the As-As an
