Abstract

The Sn M5N45N45 Auger spectrum from the (3×3)R30°-Sn Ge(111) surface has been measured in coincidence with the corresponding 3d5 2 photoelectron. By detecting this pair at appropriate emission angles, the contribution from spin-symmetric (triplet) and spin-antisymmetric (singlet) final states can be selectively enhanced or suppressed. This dichroic effect in the Auger photoelectron coincidence spectroscopy of solids provides a probe of the local valence electronic structure with element, chemical states, emission depth, and spin selectivity. The consequences and applications of this dichroic effect are discussed.
