WebFeb 1, 1978 · These electron affinities are quantitatively related to the measured flatband potentials by considering the effects of specific adsorption of potential‐determining ions (for metal oxides used in photoelectrolysis, these are usually OH − and H +). WebThe value of the flat band potential depends on many factors, such as the material, pH and crystal structure of the material. In semiconductors, valence electrons are located in energy bands. According to band theory, the electrons are either located in the valence band (lower energy) or the conduction band (higher energy), which are separated ...

In semiconductor physics, the flat band potential of a semiconductor defines the potential at which there is no depletion layer at the junction between a semiconductor and an electrolyte or p-n-junction. This is a consequence of the condition that the redox Fermi level of the electrolyte must be equal to the Fermi level of the semiconductor and therefore preventing any band bending of the conduction and valence band. An application of the flat band potential can be found in the deter…
