Mott schottky measurement
Nettet1. apr. 2007 · EIS, with a suitable equivalent circuit, was used to extract interfacial capacitance data (C), which was then compared with the electrode voltage via the Mott–Schottky equation (C-2 versus V). From the x-axis intercept the flat-band potential was determined to be -0.316 ± 0.033 V versus SCE. Nettet14. apr. 2024 · The resulting Schottky diodes are characterized within the glovebox (to minimize water and oxygen exposure) using an impedance spectrometer (Solartron Analytical ModuLab XM MAT 1 MHz). Film thicknesses are determined by measuring across a scratch in the film using an atomic force microscope (Bruker AFM Multimode 8).
