Interactions at the Al-S-Fe interface: S inhibition of aluminum oxidation
- Univ. of North Texas, Denton, TX (United States). Dept. of Chemistry
The deposition of aluminum on S/Fe(111) (1 x 1) at 300 K in UHV results in the formation of a disordered S-modified Al adlayer. Insertion of Al between the sulfur atoms and the Fe substrate is indicated by an increase of the S Auger signal with increasing Al deposition. Room-temperature oxidation of AlS/Fe(111) in UHV is inhibited compared to the oxidation of aluminum deposited on the sulfur-free Fe(111). The oxygen-uptake curves and variations in the S(LVV), Fe(MVV) intensities with oxygen exposure are also consistent with the insertion of the aluminum atoms between the S overlayer and the Fe substrate.
