 Zusammenfassung: We have used in-situ STM to study the changes in surface topography occurring on flame-annealed Au(1OO) electrode surfaces, for potential cycles which were limited to the double-layer region and also to potentials of surface oxidation. Even in the former case notable changes in the surface structure occur and it is inferred that anion specific adsorption plays the determining role in such processes. For the first time, STM images are presented of an oxide-covered electrode surface which, for the case of the Au(100) electrode, shows a rough, apparently amorphous form. Images recorded during the initial stages of oxide formation indicate an island-growth mechanism.
