Ferminivå
Ferminivå is a term used in solid state physics to describe the chemical potential of electrons in a material at a given temperature. It is commonly known as the Fermi level and represents the energy level at which the probability of occupation by an electron is significant according to the Fermi-Dirac distribution. At zero temperature, the Ferminivå corresponds to the highest occupied energy level in a system of non-interacting electrons; at finite temperatures, the occupancy around this energy is governed by thermal statistics.
In metals and degenerate semiconductors, the Ferminivå lies near the wing of the electronic structure where
In semiconductors, the Ferminivå provides a convenient reference for understanding intrinsic and doped materials. For intrinsic
