被引用回数:4 パーセンタイル:9.24(Chemistry, Physical)The local and intemediate-range atomic structure in the Ag ion conduction glasses Ag(GeSe) with 0.15 and 0.50 has been investigated by Anormalous X-Ray Scattering experiments at the K absorption edges of each constituent element. This method can provide insight into the structural properties enableing the effect of superionic conductivity for compositions with 0.33 in the amorphous phase. The experimental results were analyzed with Reverse Monte Carlo modeling, providing the partial structure factors and the corresponding partial pair-distribution functions. Evidence is found for a high level of intermediate range order for low silver concentrations, whereas the superionic conducting phase formed at high silver concentrations is characterized by cluster-like configurations of Ag atoms on a nanometer scale.

被引用回数:6 パーセンタイル:30.3(Materials Science, Ceramics)Anomalous X-ray scattering experiments on amorphous Ag(GeSe) at the K absorption edges of each constituent element has been performed to investigate the local- and intermediate-range structure in this material. This method can provide insight into the structural properties enabling the effect of superionic conductivity in the amorphous phase. The experimental results were analyzed with reverse Monte Carlo modeling, providing the partial structure factors and the corresponding partial pair-distribution functions. A nanometer range phase separation tendency of the Ag atoms over a background of a GeSe tetrahedral network is observed, which may confirm the view of Ag conduction pathways forming in this phase.
