Abstract: Using monochromatized synchrotron radiation (30 eV\ensuremath{\le}h\ensuremath{
u}\ensuremath{\le}52 eV), we have measured uv photoemission of the valence bands and shallow-core levels of the Pb/Si(100)2\ifmmode\times\else\texttimes\fi{}1 system during the initial stages of interface formation at \ensuremath{\sim}280 \ifmmode^\circ\else\textdegree\fi{}C. We have analyzed the shape of the spectra and the intensity of the Pb 5d emission which we compare with Auger electron spectroscopy data. The results show that the system is unreactive and the growth proceeds according to a layer-plus-island mode. We show also evidence of the metallization of the surface beyond monolayer coverage.
