The Kikuchi pattern, which is created by the result of inelastic scattering and dynamical diffraction of electrons, includes structural and elemental information about the surface. The Kikuchi envelope related to the surface wave resonance (SWR) is considered to include detailed information about the topmost surface. The Kikuchi pattern has been simulated based on dynamical diffraction theory. It is shown that the simulated pattern agrees with the observed pattern very well. Comparison between the simulated and observed patterns confirms that that the Kikuchi envelope under the SWR for the reconstructed surface shows the influence of the local surface potential formed by the adsorbate, where the surface wave propagates within the surface reconstructed layer with a thickness of 0.2 nm.
