Kikuchi lines are formed in diffraction patterns by diffusely scattered electrons, e.g. as a result of thermal atom vibrations. The main features of their geometry can be deduced from a simple elastic mechanism proposed in 1928 by Seishi Kikuchi , [4] although the dynamical theory of diffuse inelastic scattering … Meer weergeven Kikuchi lines are patterns of electrons formed by scattering. They pair up to form bands in electron diffraction from single crystal specimens, there to serve as "roads in orientation-space" for microscopists … Meer weergeven The figure at left plots Kikuchi lines for a larger section of silicon's orientation space.
