9450412 The proposed research encompasses the synthesis of pseudo-ternary compounds of the silver chalcogenides and the characterization and simulation of their physical and electrical properties. The ultimate aim is to relate structural information to the ionic conductivity and diffusivity of silver to obtain a deeper understanding of the mechanism of superionic conductivity which marks high temperature phases in the system Ag2S---Ag2Se--Ag2 Te. Data sets derived from x-ray diffraction,calorimetry, four-probe conductivity and x-ray absorption spectroscopy analyses will be incorporated into a computer model of the super ionic phases.

9450412所提出的研究包括银硫属化物的伪三元化合物的合成及其物理和电学性质的表征和模拟。最终的目的是将结构信息与银的离子电导率和扩散率联系起来，以更深入地理解超离子电导率的机制，该机制标志着Ag_2S-Ag_2Se-Ag_2 Te系统中的高温相。 来自X射线衍射，量热法，四探针电导率和X射线吸收光谱分析的数据集将被纳入超离子相的计算机模型。
