Resumen:
We report an independent-electron model calculation of the L2,3VV Auger lineshape for an ideal Si(100) surface. Valence states were calculated for a cluster of Si atoms using the extended Hückel approximation. Atomic Auger matrix elements were evaluated using the Clementi wave functions for the Si atoms and a Coulombian wave for the continuum wave function. Fairly good agreement between theoretical results and experimental data is found when the presence of the free surface is taken into account.
