Interface atom mobility and charge transfer effects on CuO and Cu(2)O formation on Cu(3)Pd(111) and Cu(3)Pt(111)

We bombarded [Formula: see text] and [Formula: see text] with a 2.3 eV hyperthermal oxygen molecular beam (HOMB) source, and characterized the corresponding (oxide) surfaces with synchrotron-radiation X-ray photoemission spectroscopy (SR-XPS). At [Formula: see text] , CuO forms on both [Formula: see...

description We bombarded [Formula: see text] and [Formula: see text] with a 2.3 eV hyperthermal oxygen molecular beam (HOMB) source, and characterized the corresponding (oxide) surfaces with synchrotron-radiation X-ray photoemission spectroscopy (SR-XPS). At [Formula: see text] , CuO forms on both [Formula: see text] and [Formula: see text] . When we increase the surface temperature to [Formula: see text] , [Formula: see text] also forms on [Formula: see text] , but not on [Formula: see text] . For comparison, [Formula: see text] forms even at [Formula: see text] on Cu(111). On [Formula: see text] , [Formula: see text] forms only after [Formula: see text] , and no oxides can be found at [Formula: see text] . We ascribe this difference in Cu oxide formation to the mobility of the interfacial species (Cu/Pd/Pt) and charge transfer between the surface Cu oxides and subsurface species (Cu/Pd/Pt).
