Figure 2
Auger electron spectrum obtained at a photon energy of 7903 eV from CoAlPO-34 A. Two different energy windows for Auger electron spectra for each primary photon beam are indicated. The decision about the number and width of energy windows is based on the quality of data, i.e. signal-to-noise ratio and objectives of the study, for instance, the depth profiling of the sample. The low-energy region is the Auger electrons which escape from the bulk, whereas the higher-energy electrons emanate from the near-surface region of the sample. |
