Mott−schottky measurements
NettetMott-Schottky Purpose. The Mott-Schottky technique is used to measure the changes that occur in an electrochemical interface as its DC voltage is changed. A fixed-frequency, small-signal AC potential excitation is applied to an electrochemical cell. The impedance of the working-electrode interface is measured as a function of DC voltage.
