Abstract:

A scanning electrochem. microscope (SECM) has been applied to the local deposition of Co microstructures on Au. The method employs a Co microelectrode to generate a potential-controlled flux of the resp. ions in an aq. soln. The microelectrode was positioned at a precisely defined distance above a gold surface using the steady-state current for oxygen redn. The optimum conditions for Co dissoln. and deposition were identified from voltammetry and chronoamperometry. Applying these conditions in the SECM configuration facilitated the successful deposition of Co structures. The dissoln. and uptake of Co on the Au surface was investigated using SECM double potential step chronoamperometry. [on SciFinder(R)]
