Scanning Electrochemical Microscopy: Fitting Rg with Negative Feedback Curve
Scanning Electrochemical Microscopy: Fitting Rg with Negative Feedback Curve
In scanning electrochemical microscopy (SECM), Rg is defined as the ratio between the insulator thickness and the radius of the microdisk electrode. This Demonstration shows how to manually or automatically fit Rg by using the approximation for negative feedback current, which is a function of the tip-substrate distance and Rg.
