Abstract
SIMS in the low damage mode is applied to characterize different surface arrangements of O on a heated polycrystalline Pt 3Pb sample which is exposed to several oxygen doses. Small oxygen doses at 600 K lead to a surface characterized by O in on-top positions principally. At higher doses oxygen saturation occurs which is probably accompanied by a transition to a reconstructed state of the treated surface. At 790 K immediately place-exchange between O and the substrate metal atoms happens after all doses supplied. The SIMS results are elucidated using recent presentations of the interaction of electronegative species with metallic surfaces. The connection between work function and oxygen surface arrangement is discussed in detail.
