T. Okuda et al., SURFACE CORE-LEVEL SHIFTS OF THE AU ADSORBED SI(111) RECONSTRUCTED SURFACES, Journal of electron spectroscopy and related phenomena, 80, 1996, pp. 229-232
By means of synchrotron radiation we have performed surface sensitive
Si 2p core photoelectron spectroscopy of the Si(111)5x2-Au, alpha-root
3x root 3-Au, beta-root 3x root 3-AU, and 6x6-Au surfaces systematica
lly and determined their surface core level shifts(SCLS) by curve fitt
ing. From the results we discuss about their electronic and geometric
structures and compare our results with the so far proposed models for
the Si(111)root 3x root 3 and 6x6-Au surfaces especially.
