Resumen:
In this work, we propose an explanation of such detected flattening based on themembrane roughness. This roughness is reproduced on the electrodes when liquidmetal electrodes of Hg are used. On the other hand, roughness and the corresponding fractal dimension from Atomic Force Microscopy (AFM) measurements were evaluated. This fractal dimension was compared with that obtained from EISexperiments, by fitting the Nyquist lobe to a constant phase element (CPE).
