Beschreibungen/Notizen
Auger measurements have been carried out on films of the semiconducting compound tetracyanoquinodimethane in order to interpret the observed line shape on the basis of the knowledge of the valence band of this organic molecule. A comparison has been made between the experimental spectra and the theory that takes into account the final state Coulomb interaction
U between the two Auger holes. Such interaction affects the experimental line shapes which, in the unperturbed case, may be approximated by a self-convolution of the density of states. It has been found that
U is small (about 2 eV) if compared with the valence band extension (43 eV). Thus, the Auger line shape may be described, with a good degree of approximation, by the self-convolution of the valence band density of states. The agreement between theory and experiment is quite satisfactory.
