“…0.06 eV), the uptake curve shows an initial uptake (fast chemisorption stage), an intermediate plateau (oxide onset) followed by a re-increase (fast oxide growth stage) of oxygen coverage. These characteristics can be seen in previous reports [1][2][3][4]. The oxygen content at saturation has been reported to be 3 ML [4].…”

“…When the clean Ni(111) surface is exposed to O 2 gas at higher temperatures, a plateau appears in an intermediate region of the oxygen uptake curve [1]. These characteristics are also observed in the oxidation of the Ni(001) surface [2].…”

“…The Ni(111) surface reacts with O 2 molecules to form a thin oxide layer on the surface at 147 K [1] showing a Langmuir-type oxygen uptake curve. When the clean Ni(111) surface is exposed to O 2 gas at higher temperatures, a plateau appears in an intermediate region of the oxygen uptake curve [1].…”

“…4, which is in agreement with the results of Labohm et al [13]. The initial increase in 6A of 0.1' is due to to chemisorbed oxygen which precedes the incorporation of oxygen [13,14]. At a crystal temperature of 250°C and an oxygen pressure of 3 X lo-' Torr, the interaction of oxygen with the carbide layer, containing different carbon coverages, is represented in fig 2).…”

The thermal decomposition of ethylene on Ni(lll) at 250°C is shown to lead to carbon deposition on and -in a later stage -below the surface. Independent of the amount of carbon below the surface, CO is adsorbed with an isosteric heat of adsorption of 105 kJ/mol. The surface carbon reacts with oxygen at 25O'C. The reaction rate is independent of the surface carbon coverage and first order in oxygen pressure. The subsurface carbon segregates to the surface after removal of the surface carbon layer.

Static friction experiments were performed in ultrahigh vacuum at room temperature on copper, iron, and steel contacts selectively contaminated with oxygen and chlorine in submonolayer amounts. The concentration of the adsorbates was determined with Auger electron spectroscopy and was measured relative to the saturation concentration of oxygen on iron (concentration 1. 0). The coefficient of static friction decreased with increasing adsorbate concentration. It was independent of the metal and the adsorbate. The results compared satisfactorily with an extension of the junction growth theory to heterogeneous interfaces. The reduction in interfacial shear strength was measured by the ratio Sa/sm, where sa is the shear strength of the interface with an adsorbate concentration of 1. 0, and s m is the strength of the clean metal interface. This ratio was 0.835±0. 012 for all the systems tested.
