TRANSIENT-BEHAVIOR AT PLANAR MICROELECTRODES - DIFFUSION CURRENT AT A BAND ELECTRODE BY AN INTEGRAL-EQUATION METHOD .2.

We have previously formulated an integral equation method for the calculation of current in response to a potential step at a microelectrode and have applied it to obtain the diffusion-limited current at a band electrode. For systematic application to other electrode boundary conditions and cell geometries, generic programs for solution of relevant integral equations and inversion of resulting Laplace transforms have been developed. In this paper, we report on initial uses of these new programs for the band electrode case, including calculation of diffusion-limited current over a range 40 times greater than our earlier report and comparison with experiment. © 1990.
