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

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