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拟议的研究涵盖了银色葡萄糖代化的伪内化合物的合成以及其物理和电性能的表征和模拟。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，以更深入地了解超电联电导率的机理，该机理标记了系统AG2S中的高温相--- AG2SE-AG2 TE。 源自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纳入超级离子相的计算机模型中。
