Flat-Band Potential of a Semiconductor: Using the Mott–Schottky Equation
Journal of Chemical Education, 2007Semiconductors are an important category of materials involved in many applications in modern society. One such application revolves around the search for efficient sustainable forms of energy, in this case the use of semiconductors to assist in the conversion of light to electrical energy.

Mott–Schottky analysis of polycrystalline copper(I) bromide in aqueous electrolytes
Journal of Electroanalytical Chemistry, 1998Abstract Polycrystalline electrodes of copper(I) bromide were investigated at room temperature in aqueous electrolytes. After long-time stabilisation in a 0.001 M CuSO 4 solution, an open-circuit potential of about 0.27 V (SHE) was observed. Nonideal interfacial capacitance values were determined from impedance measurements at frequencies between ...

Semiconductors and Mott-Schottky Plots
2013When a conductive electrode (e.g., metallic or glassy carbon) is in contact with an electrolytic solution, the excess electronic charge is accumulated at the electrode surface and charge distribution occurs in the solution only. This is related to the fact that as the number of charged species increases, the space in which the redistribution of charges

The Preparation of TiO2 Electrodes with Minimum Mott‐Schottky Frequency Dispersion
Journal of The Electrochemical Society, 1982A preparation procedure for is described which produces electrodes with nearly ideal Mott‐Schottky plots in . The Mott‐Schottky plots are linear and exhibit slopes and intercepts nearly independent of applied frequency from 105 Hz to 50 KHz. Based on Mott‐Schottky intercepts and photocurrent onset potentials, vs. SCE in . Frequency dispersion increases

Measurement method for carrier concentration in TiO2 via the Mott–Schottky approach
Thin Solid Films, 2011Abstract In direct contrast to the way in which silicon is precisely doped for integrated circuit applications in order to optimize device performance, there is little nuanced understanding of the correlation between TiO 2 doping level, charge carrier concentration, and the operation of TiO 2 -based photocatalysts, dye-sensitized solar cells, and ...

Limitations of Mott-Schottky Analysis for Organic Metal-Insulator-Semiconductor Capacitors
2019The application of Mott-Schottky (MS) relation in organic devices often leads to erroneous results. In particular, the doping density, extracted using this method found to vary with the thickness of semiconductor. We address the limitations in using MS relationship for organic metal-insulator-semiconductor (MIS) capacitors as a consequence of deviation

Homologous heterostructures of Ni/NiFeO Mott–Schottky for alkaline water electrolysis
Journal of Materials Chemistry AAn in situ strategy is proposed to fabricate a Mott–Schottky Ni/NiFeO catalyst composed of Ni nanoparticles over NiFeO nanosheets, which leads to charge transfer from Ni to Fe and promotes the bifunctional activity for the HER and OER.

Surface treatment of Si by annealing and effect on Mott-Schottky plots
Electrochimica Acta, 1992Abstract Annealing has a healing effect on the surface of p-Si. This leads to a shift of the flatband potential of up to 2V. This effect was studied by capacitance measurements (Mott—Schottky plots) on p-Si samples in acetonitrile in a wide range of acceptor concentrations from NA = 1 E+21 up to NA = 1 E+25.
