ABSTRACTA technique commonly used as the final stage of cleaning gold electrode surfaces is to electrochemically form and reduce a monolayer of oxide on the surface. We have investigated the changes on the Au(111) surface during this procedure using in situ electrochemical scanning tunneling microscopy.

We report the potential and concentration controlled assembly of an alkyl-substituted benzo[1,2-b:4,5-b′]dithiophene (DDBDT) on an Au(111) electrode byin situelectrochemical scanning tunneling microscopy (ECSTM).
