Theory of square, rectangular, and microband electrodes through explicit GPU simulation

The use of microband electrodes in electrochemistry has expanded in recent years due to enhanced current densities, ease of fabrication, and available theory. This paper, through explicit three-dimensional finite difference GPU simulation, simulates mass transport to square and rectangular (finite band) microelectrodes and quantifies the response of a finite band at any given length to width ratio, including the validation of an equation for the chronoamperometric response. In addition, the power of explicit simulations harnessed to modern computing hardware is emphasised.
