Abstract : The underpotential deposition of lead onto very clean and well-ordered single crystal Au samples was studied with linear sweep voltammetry. The single crystal surfaces examined were (100), (110), (111) and (410). The (410) surface is a stepped surface with terraces of (100) orientation four atomic rows in width separated by steps of (100) orientation of monatomic height. The crystals were prepared in an ultra-high vacuum environment (equivalent to 10 to the minus 11th power Torr) by alternate cycles of argon-ion sputtering and annealing until the surfaces were clean within the limits of AES (Auger Electron Spectroscopy).
