Noun
Fermi level (plural Fermi levels)
The total chemical potential for electrons.
BCS theory relates the value of the critical field at zero temperature to the value of the transition temperature and the density of states at the Fermi level. Source: Internet
In order to move from the hot emitter to the vacuum, an electron's energy must exceed the emitter Fermi level by an amount : determined simply by the thermionic work function of the emitter. Source: Internet
Doping and gating move either the conduction or valence band much closer to the Fermi level, and greatly increase the number of partially filled states. Source: Internet
Depletion seeAlso As described above, and shown in the figure, with sufficient gate voltage, the valence band edge is driven far from the Fermi level, and holes from the body are driven away from the gate. Source: Internet
Furthermore, it describes how the density of states is changed on entering the superconducting state, where there are no electronic states any more at the Fermi level. Source: Internet
In other words, tunneling occurs mainly with electrons of energies near the Fermi level. Source: Internet
