A New in Situ Optical Microscope with Single Atomic Layer Resolution for Observation of Electrochemical Dissolution of Au(111).

Monatomic steps with a height of 0.25 nm on ultraflat Au(1 11) surfaces during electrôchemical dissolution can be seen for the first time by a laser confocal microscope combined with a differential interference contrast microscope (LCM-DIM). Atomic force microscopy images were acquired in the same a...

Sumario:Monatomic steps with a height of 0.25 nm on ultraflat Au(1 11) surfaces during electrôchemical dissolution can be seen for the first time by a laser confocal microscope combined with a differential interference contrast microscope (LCM-DIM). Atomic force microscopy images were acquired in the same area in order to confirm that the step lines observed by LCM-DIM are mostly monatomic steps with the height of 0.25 nm. Successively recorded LCM-DIM images indicated that the anodic dissolution of Au(1 11) takes place only at step edges in solutions containing chloride anions at potentials near the onset of anodic current.
