EXPERIMENTAL STRATEGIES FOR CONTINUOUS MEASUREMENTS OF I-T TRANSIENTSOF A SILVER SINGLE NUCLEUS ON CARBON MICROELECTRODES

Potential step and in situ atomic force microscopy measurements were e mployed to study the nucleation and subsequent behaviour of a silver s ingle nucleus on carbon microelectrodes. It was shown that the precedi ng electrodeposition process on the carbon microelectrode strongly aff ects the subsequent nucleation and growth behaviour. A method of destr oying or avoiding this historic effect of the substrate was developed. It provides a new way of performing a large number of electrochemical measurements without mechanical polishing and manual interference, an d therefore facilitates further more detailed studies of a system whic h requires continuous and automatic l-t transient measurements of stat istical meaning. It was demonstrated that secure and automatic statist ical measurements of l-t transients could be fulfilled utilising the m ethod.
