Using reflection high-energy electron diffraction (RHEED), we demonstrate the behavior of a wave field formed on a graphite crystal surface. The sample used is highly oriented pyrolytic graphite, which is a polycrystalline (mosaic crystal) with a few micrometers-sized domain rotated on a plane. One-beam dynamical calculation is proved to be effective for analyzing the distance between the atomic planes. One-beam dynamical calculation is also used to obtain a wave field, which is incident electron density distribution, for surface normal direction. The characteristic behavior of the wave field at Bragg conditions is demonstrated by the Auger electron intensity of carbon excited by RHEED incident electron beam. This can be measured by changing the glancing angle using beam rocking Auger electron spectroscopy (BRAES). It has been found that the anomalous intensities in the measured BRAES profile almost correspond to the calculated wave field intensities on the atomic planes.
