Research output: Contribution to journalJournal articleResearchpeer-review


The atomic geometry of the Al(111)-(√3 x√3)R30 degrees phase formed by adsorption of one-third monolayer Cs on Al(111) at 100 K has been determined by analysis of extensive low energy electron diffraction (LEED) measurements. Cs atoms are found to occupy on top sites on a rumpled first layer Of Al atoms. The structure is similar to those of the corresponding (√3 x√3)R30 degrees phases formed by adsorption of K and Rb on Al(111) at low temperature. [S0163-1829(98)01540-9].
