Abstract

The Auger electron intensities of Si-LVV and Ag-MNN from a Si(111)7×7 and a Si(111)√3×√3-Ag surfaces were measured for varying glancing angles of the incident electron beam in reflection high-energy electron diffraction, known as the beam rocking Auger electron spectroscopy (BRAES). The energy of incident electron beams used was 10 and 5 keV. The intensity anomalies observed in these BRAES profiles on the surface wave resonance condition were more pronounced for the 5-keV incident beam than for the 10-keV beam. It was found from BRAES profiles of the Si(111)√3×√3-Ag surface by the 5-keV incident beam that the intensity enhancements of Si-LVV differed from those of Ag-MNN at the [112] incidence, but were similar at the [101] incidence. This result can be interpreted qualitatively by the wave field periodicity parallel to the surface. (Figure Presented).
