The Sn M5N45N45 Auger spectrum from the (root 3 x root 3)R30 degrees-Sn/Ge(111) surface has been measured in coincidence with the corresponding 3d(5/2) 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.

Abstract
The Sn M5N45N45 Auger spectrum from the (root 3 x root 3)R30 degrees-Sn/Ge(111) surface has been measured in coincidence with the corresponding 3d(5/2) 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
