X-Ray Standing Wave Studies of Underpotentially Deposited Metal Monolayers

Abstract

The x-ray standing wave technique has been employed in the study of the structure of underpotentially deposited (UPD) copper on an iodine covered platinum surface and of copper on a Au(100) single crystal electrode. For Cu UPD on Pt, surface coverage isotherms derived from both electrochemical and x-ray measurements are compared. The growth mode of the copper ad-layer appears to be strongly influenced by the electrode's surface morphology. For Cu UPD on Au(100) the coherence of the adlayer is strongly dependent on the mode of deposition.
