RIMI: Synthesis, Characterization, and Simulations of Silver Chalcogenides, Ag2(S,Se,Te)

9450412拟议的研究包括合成硫族银的伪三元化合物，并对其物理和电学性质进行表征和模拟。最终目的是将结构信息与银的离子电导和扩散系数联系起来，以更深入地了解标志着Ag2S-Ag2Se--Ag2Te系统高温相的快离子电导机制。来自X射线衍射、量热、四探针导电性和X射线吸收光谱分析的数据集将被合并到超级离子相的计算机模型中。

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.
