Influence of Surface Plasmon on Kikuchi Pattern in RHEED

The Kikuchi pattern gives a lot of information about diffracted waves under different incident conditions, because the forms by inelastic scattered electrons having various directions. By analyzing intensity pattern, equivalent to results measured many conditions can be obtained. To analyze it is necessary know scattering cross-section. As first step, we estimated “apparent” cross-section in comparing with dynamic diffraction calculation. In formation patterns, although phonons and bulk plasmons mainly contribute lines, has been suggested that surface have significant influence on envelope.
