The lecture focuses on diffraction and scattering phenomena in materials science beyond basic Bragg diffraction. Introducing the Born approximation and Kirchhoff’s theory, diffraction from ideal and non-ideal crystals is treated including, e.g., temperature and size effects, ordering phenomena, small-angle scattering and dynamical diffraction theories for both electron and X-ray diffraction.

A comprehensive understanding of the interaction of electrons and ions with condensed matter and details on the instrumentation and methods designed to scan, transmit, and point-project these probes for the structural and chemical analysis of various materials.

This advanced course on High Resolution Transmission Electron Microscopy (HRTEM) provides lectures focused on HRTEM and HRSTEM imaging principles, related data analysis and simulation and phase restoration methods.

The main aim of the course is to enable the students to independently choose a suitable material characterization methods to address a specific materials science question. Subject areas are: light microscopy, diffraction methods (X-rays, neutrons, electrons), electron microscopy, atom probe tomography and atomic force microscopy. Depending on lecturer, lectures and practicals in German or English.
