title: Accurate and simplified consideration of the probe geometrical defaults in scanning electrochemical microscopy: theoretical and experimental investigations.
abstract: Fabrication of scanning electrochemical microscopy (SECM) tips cannot always guarantee a perfect disk geometry. In the present work, the impact of these defaults is investigated both theoretically and experimentally. The situations where these defaults can accurately be taken into account by considering that the probe behaves like a microdisk with effective geometric parameters are determined. In these situations, the quantitative analysis of the experimental results is greatly simplified. The study also proposes expressions to evaluate the apparent microdisk parameters from a picture of the probe.
