Dynamical Scattering

This lecture covers the concept of dynamical scattering in electron diffraction, where electrons interact strongly with matter, leading to multiple scattering events. The lecture explains how scattering and intensities in different diffracted beams are interdependent, making interpretation challenging. Topics include thickness fringes, bend contours, double diffraction, and crystal phase discrimination. Examples are provided to illustrate these phenomena, such as the formation of satellite spots and bend contours in dark-field images. The lecture also discusses the applications of electron diffraction in studying crystal defects, crystal phases, and epitaxial relationships.
