Surface X-ray scattering (SXS) and scanning tunneling microscope (STM) studies have been carried out to determine the structure of electrochemically deposited Bi monolayers on a Au(111) electrode. Between 10 and 190 mV (relative to bulk deposition), a uniaxially commensurate rectangular phase is formed in which the Bi coverage decreases from 0.646 to 0.616 relative to a gold monolayer. A 25% coverage (2 [times] 2) phase is stable between 200 and 280 mV. The structures determined by SXS and STM are in agreement with those determined previously by AFM. 15 refs., 5 figs.
