Mott schottky flat band potential
Nettet1. mai 1978 · Flatband potentials and donor densities were determined from Mott‐Schottky plots and evidence for deep and shallow donors is presented. Potentials of zero photocurrent were determined using chopped light and were in excellent agreement in basic solution with flatband potentials calculated from 1 kHz capacitance measurements. Nettet13. jul. 2024 · Mott-Schottky (MS) was also performed to study the flat bands of MCS and MCS/0.5 MXene.From the Fig. 9c, compared with that of pure Mn0.2Cd0.8S (−1.25 eV), the flat band potential of MCS/0.5 MXene is more negative(−1.62 eV), indicating that the composite of MCS/0.5 MXene has much stronger reduction capacity.
