Summary

Description
English: Mott-Schottky plot of a fluor-doped tin oxide (FTO) semiconductor electrode measured in aqueous electrolyte at different pH, with respect to standard Ag/AgCl electrode. Changing the pH modifies the apparent flatband potential by 570 mV corresponding to a 59 mV displacement per unit of pH. From the slope the donor density ND = 1.0x1021 cm-3 is determined. Then the same sample is measured after nanostructured TiO2 is deposited on top of FTO. The observed change of slope is due to the decrease of the surface in direct contact with the electrolyte.
