Title: Structure and Lattice Dynamics of Copper- and Silver-based Superionic Conducting Chalcogenides
Language: English
Abstract:

The high-temperature crystal structure and lattice dynamics of superionic silver- and copper-based chalcogenides have been investigated by powder diffraction and inelastic neutron scattering. The obtained issues provide the experimental background for understanding of correlations between microscopic phenomena and macroscopic properties (ionic conductivity, thermodynamics, and thermal expansion). Moreover, these experimental results are an experimental base for further experimental (total scattering) and computational (molecular dynamics simulations) investigations of cation diffusion in superionic silver- and copper-based chalcogenides.

Kristallstruktur und Gitterdynamik von Silber- und Kupferchalkogenid Ionenleitern wurden mittels Pulverbeugung und unelastischer Neutronenstreuung untersucht. Die erhaltenden experementellen Ergebnisse liefern die experimentelle Basis für das Verstandnis der Korrelationen zwischen mikroskopischen Phänomenen und makroskopischen Eigenschaften (ionische Leitfähigkeit, Thermodynamik und thermische Ausdehnung). Darüber hinaus stellen diese Resultate den experimentellen Grund für weitere experimentelle (total scattering) und rechenbetonte (Molekulardynamik) Untersuchungen über den Ionentransport in den untersuchten Kupferselenid-Legierungen dar.German
