Beschreibungen
We have studied carbon KVV Auger electron emission from highly oriented pyrolytic graphite (HOPG) by ion-induced 180° electron spectroscopy. In obliquely emitting directions across the HOPG (0 0 0 1) surface, the Auger peak yield induced by MeV protons becomes lower than in the surface normal direction. An analysis based on mean free path for inelastic scattering indicates that the observed reduction of the Auger yield can be explained by increased inelastic collisions with valence electrons above the surface. The experimental results provide information about the production sites of the KVV Auger electrons in the layer structure.
