Mott schottky flat band potential
NettetA linear Mott-Schottky plots (1/C 2 in a function of applied potential), typically observed for flat samples [132], were achieved for as-grown nanorods. The donor density in these samples was found to increase from 5 × 10 18 cm −3 to 2.4 × 10 20 cm −3 when the KCl concentration in the deposition bath was changed from 0.05 M to 3.4 M, respectively ( … Nettet10. aug. 2016 · The effect of the above mentioned electrolytes on the flat band potential of TiO 2 was determined by the Mott-Schottky analysis. To acquire the Mott-Schottky plot electrochemical impedance spectroscopy was done by using PGSTAT (302 N Metrohm Autolab) for potential varying from −200 mV to −800 mV at 1 KHz frequency. …
