Abstract

The atomic radial distribution function of vitreous AgGeAsSe₃, obtained based on the experimental intensity curves taken with monochromatic copper and molybdenum radiation, is interpreted using a fragmentary model in the entire ordering region (~9 Å). It is shown that the glass consists of selenium and selenium-arsenic tetrahedra with germanium and silver atoms inside. The spatial arrangement of such tetrahedra in glass within the ordering region is similar to their arrangement in the GeAsSe and GeSe₂ structures. It is proposed that the “openwork” structure of the fragments of these structures allows the movement of Ag⁺ ions (ionic conductivity) in vitreous AgGeAsSe₃. Fragments of the structure of the ion-conducting compound Ag₂Se are not found in the studied glass.

离子导电半导体玻璃AgGeAsSe3原子结构的碎片模型

摘要

_{玻璃体 AgGeAsSe 3}的原子径向分布函数是根据单色铜和钼辐射的实验强度曲线获得的，使用整个有序区域 (~9 Å) 的碎片模型进行解释。结果表明，该玻璃由硒和硒砷四面体组成，内部有锗和银原子。_{玻璃中这种四面体在有序区域内的空间排列与它们在GeAsSe和GeSe 2}结构中的排列相似。提出这些结构的片段的“镂空”结构允许Ag ⁺离子在玻璃体AgGeAsSe ₃中移动（离子电导率） 。在所研究的玻璃中没有发现离子导电化合物Ag _{2 Se 的结构片段。}
