Abstract

Anomalous behaviors of Auger intensities have been observed for ZnO(0001) surface depending on the glancing angle of incident electron beam of RHEED. In the beam rocking Auger electron spectroscopy, BRAES, the profiles of Zn(LMM) and O(KLL) were compared with each other. It was found that their profiles differed in some aspects. This suggests that their Auger intensities are influenced by the wave field of incident electron beam of RHEED. In this study, RHEED rocking curves were also measured and analyzed by dynamical calculations. It has been found that the determination of surface polarity is possible by RHEED rocking curves.
