Scanning Electrochemical Microscopy Approach Curves Numerically Simulated for Ring Microelectrodes in Pure Negative and Positive Feedback Mode

Abstract

Herein we report an extensive data set from numerical simulations of the ring microelectrode for pure positive and negative feedback mode approach curves. The dependence of the resulting simulated approach curves with characteristic dimensions of the ring microelectrode is also given. An analysis of the impact of the internal void of the pipette over the current distribution is made.
