Abstract
The atomic geometry of the Al(111)-(√3x√3)R30° phase formed by adsorption of one-third monolayer Li on Al(111) at room temperature has been determined by analysis of extensive low-energy electron-diffraction measurements. The structure is found to be a binary surface alloy, in which Li atoms occupy sixfold coordinate substitutional sites formed by displacing every third Al atom in the first layer of the substrate, similar to the structures found previously for the corresponding (√3x√3)R30° phases formed by adsorption of Na, K, and Rb.
