The deposit of Bi adatoms by UPD on Ru, was systematically studied as function of the potential and time of deposition. The UPD Bi was characterized by a monolayer peak at 0.60 V and with an UPD shift ΔE p = 0.36 V. The electrochemical behaviour of the Bi adsorbed layer, the stoichiometry for the Ru/Bi system and a possible rearrangement of Bi, are discussed.
