摘要：

Atomic structures of an underpotentially deposited Cu adlayer on a Au(111) surface have been investigated using in situ atomic force microscopy. A Cu(1 x 1) structure adlayer is atomically resolved just before starting the bulk deposition. We demonstrated that the first full Cu monolayer on Au(111) is a pseudomorphic (1 x 1) layer in an aqueous sulfuric acid solution. We have confirmed that a Cu(5 x 5) phase adlayer has been induced by Cl- in the solution.
