| heal.abstract | The interaction of oxygen with evaporated Ni films on an Fe-doped SrTiO3 (100) substrate was investigated by means of LEED, AES and work function measurements (WF) at room temperature. The adsorption of oxygen takes place on the nickel overlayer firstly by chemisorption on nickel step sites, accompanied by a reduction of the WF, and secondly on terrace sites, followed by a WF increase. After the chemisorption phase, the oxidation of the nickel overlayer starts with NiO island formation followed by bulk NiO development, which is marked by a second WF reduction. The adsorption phase's of oxygen correspond closely to those of oxygen on single crystals of nickel. This indicates that the-character of the Ni predeposited layers on strontium titanate seems to be metallic. | en |
