What is the specific reason for the enhancement of peak of electrode modified with material + analyte in CV measurements (Ferro/Ferri solution) ?

I want to ask about the response of the analyte in the EIS measurement. Bare shows a high Rct response as compared to material-modified electrodes. But when we modify the material + analyte, the...
