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… WebHighlights: • Surface potential changes can be detected from HAXPES measurements. • Flat band voltage shifts can be detected from HAXPES measurements. • Agreement between HAXPES and C–V measurements in Si based MOS structures. • Agreement between HAXPES and C–V mea elaine s art work
