Abstract
Mercury microelectrodes, fabricated by electrodeposition on an inlaid disk, adopt the shape of a sphere cap. This article derives the steady -state diffusion-limited voltammetric current at such electrodes and c orrelates the current with the radius, area, and volume of the sphere cap. Also predicted are the steady-state currents at an entire sphere emerging from an insulating plane.
