Auger spectroscopy of strongly correlated systems: present status and future trends

We review the Cini-Sawatzky approach to the line shape analysis of Auger CV V transitions, in its basic and original formulation. Then, several extensi ons of the theory are reviewed, namely the inclusion spin-orbit coupling, d ynamical/ plasmon screening, overlap effects, off-site interactions, the tr eatment of disorder and the formulation for partially filled bands. We conc lude by highlighting what we consider to be future directions in the field. (C) 2001 Elsevier Science B.V. All rights reserved.
