To extract the maximum amount of information from experimental electron backscatter diffraction (EBSD) patterns, it is necessary to realistically model the physical processes that lead to the formation of the characteristic diffraction features in the form of Kikuchi bands and lines. Whereas the purely geometrical relations in the observed networks of bands and lines can be explained by mapping out Bragg’s law for the relevant reflecting lattice planes, the dynamical theory of electron diffraction is needed to explain the observed intensities. This theory takes into account the fact that electrons interact strongly with matter, which leads to multiple elastic and inelastic scattering of the electron waves in a crystal.
