HARMONY OF IN-SITU STM AND ELECTROCHEMICA L OBSERVATIONS ON SINGLE-CRYSTAL GOLD ELECTRODES

From observations of hysteresis or alternative signal frequency disper sion on differential capacity-potential curves, it was suggested that (100), (111) and (110) gold faces change their atomic superficial arra ngements at the electrochemical interface in the double layer region o f potential. In situ STM images of these gold faces obtained with X. G ao and M.J. Weaver allowed to describe the nature and the kinetics of these superficial atomic structural changes.
