Abstract
The first observation of Si(111) 7×7 intrinsic surface states that uses Auger electron spectroscopy as a valence band spectroscopy is reported. A global inversion method based upon the fast Fourier transform was used to self-deconvolve the Auger spectra. Subsequent oxygen chemisorption is shown to give rise to electronic levels. Only at the beginning of the oxidation stage are the surface states completely removed.
