为了研究Ag_x（GeSe_3）_（1-x）超离子玻璃的非均匀结构与导电路径形成的关系，对各组分进行了X射线衍射、中子衍射和K边EXAFS测量。基于这些实验数据的反向Monte Carlo结构模拟表明，Ag导电路径形成在GeSe 4四面体网络的随机玻璃介质中。第一个尖锐衍射峰（FSDP）位于1.1 <$-1处，主要由GeSe_4网络贡献，而观测到的强烈小角散射也是由Ag-Ag和GeSe_4网络贡献的。
To investigate relation between inhomogeneous structure of Agx(GeSe3)1-xsuperionic glass and conduction path formation, x-ray diffraction, neutron diffraction and EXAFS measurements onK-edges for each constituent were performed. Reverse Monte Carlo structural modelling based on these experimental data revealed that Ag conduction paths are formed in random glass media of GeSe4tetrahedral network. The first sharp diffraction peak (FSDP) located at 1.1 Å-1is mainly contributed by GeSe4network, while an observed intense small angle scattering is contributed also by Ag-Ag as well as GeSe4network.
