Flat band potential 意味
WebAug 12, 2024 · Flat bands facilitate the emergence of strongly correlated electronic phases 18, 19, 20. A celebrated example is the Landau-level (LL) sequence of magnetically induced flat bands that can host ... 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…
