摘要：

The ordering of Bi on a Si(111)-7 x 7 surface was studied as a function of overlayer coverage and deposition conditions using low-energy electron diffraction (LEED) and Auger electron spectroscopy. We observed a one-third-monolayer and a saturated one-monolayer phase. Both phases displayed identical square-root 3 x square-root 3-R30-degrees LEED symmetries. LEED intensity data were used to differentiate between the two phases and to determine a quantitative atomic geometry via a thorough dynamical LEED analysis.
