Abstract
The microstructure and resulting physical properties of nanostructured functional ceramic are strongly defined by the nature of structural and compositional imperfections on the atomic level. In view of this, the aim of the proposed project foresees studies of chemical composition and structure in technologically important nanostructured functional ceramic with atomically resolved Z-contrast (HAADF-STEM) imaging where structure and composition are simultaneously characterized on the atomic scale. In order to reconstruct the structure and the composition of the investigated material properly, an exact HAADF-STEM image interpretation algorithm will be developed, based on the quantitative correlation between simulated and experimental HAADF-STEM images. The result will be the atomic model of the investigated defect optimized by the composition.
