Abstract

The adsorption of bismuth onto the Au(111) surface has been investigated with use of the surface techniques of Auger-electron spectroscopy, low-energy electron diffraction, electron-energy-loss spectroscopy, and work-function measurements. The interaction of oxygen with adsorbed Bi on Au(111) has also been studied to further the understanding of the Bi-Au system. The results indicate that bismuth forms a single monolayer followed by the growth of a Bi-Au compound below this layer. The monolayer is not quite close packed and BiAu is the stoichiometry suggested for the compound. These results contradict those of an earlier study which suggested that Bi forms a close-packed monolayer followed by three-dimensional island growth (Stranski-Krastanov growth).
