Scanning Electrochemical Microscopy: Diffusion on a Microdisk Electrode
Scanning Electrochemical Microscopy: Diffusion on a Microdisk Electrode
Scanning Electrochemical Microscopy (SECM) uses a microelectrode tip to image the microscopic domain. Because of the very small size of the microelectrode (of the order of micrometers) the mass transport in a disk-shaped microelectrode can be considered to occur in a semi-infinite region. This Demonstration shows the concentration profile of electroactive space during diffusion in and out of the surface of the microdisk electrode.
