Mott–Schottky plot of a fluorine-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.

Flat-Band Potential of a Semiconductor: Using the Mott–Schottky ...
Nettet3. Mott-Schottky measurement The flat band potential (Efb) of CZS: x% La photocatalysts were determined by Mott–Schottky method, which was carried out in a conventional three electrode cell using a PARSTAT-2273 advanced electrochemical system (Princeton Applied Research) equipped with an impedance analyzer. The as … Nettet13. jun. 2024 · EIS measurements at various DC voltages allow to generate Mott-Schottky plots, from which several critical characteristics of the semi-conductors can be generated as a function of the frequency: donor densities and flatband potentials.

Nettet31. jan. 2011 · Voltage ranges leading to accumulation, depletion, and inversion at the TiO 2 -metal contact are shown. Only the data taken under the depletion condition are useful for calculating carrier concentration. (b) The data in (a) plotted in conventional Mott–Schottky form. The plots are recorded at 1 MHz. NettetAbstract. A large body of literature reports that both bismuth vanadate and haematite photoanodes are semiconductors with an extremely high doping density between 10 18 and 10 21 cm −3.Such values are obtained from Mott–Schottky plots by assuming that the measured capacitance is dominated by the capacitance of the depletion layer … NettetMott-Schottky (MS) analysis is commonly employed to determine doping densities and built-in voltages in the device.
