The full-solid-angle (2pi) intensity maps of the carbon-KVV Auger-electron emission at 260 eV from diamond (111), diamond (100), and highly oriented pyrolitic graphite (HOPG) (000 1) samples were collected and compared with spherical-wave single-scattering cluster calculations. In contrast to Mg Kalpha excited C Is patterns the C-KVV patterns show weak direct real-space information. We performed a detailed angular momentum analysis taking into account different l characters of the emitted Auger electrons and show that in diamond the C-KVV emission has mainly a d-like character while graphite emits a mixture of p- and d-like electrons with a minor contribution of s-like electrons.

Abstract

The full-solid-angle (2pi) intensity maps of the carbon-KVV Auger-electron emission at 260 eV from diamond (111), diamond (100), and highly oriented pyrolitic graphite (HOPG) (000 1) samples were collected and compared with spherical-wave single-scattering cluster calculations. In contrast to Mg Kalpha excited C Is patterns the C-KVV patterns show weak direct real-space information. We performed a detailed angular momentum analysis taking into account different l characters of the emitted Auger electrons and show that in diamond the C-KVV emission has mainly a d-like character while graphite emits a mixture of p- and d-like electrons with a minor contribution of s-like electrons.
