The 18 pages that link to Fermi level, each with the reason it gives.
Band gapRelated: Its position relative to the band edges helps determine carrier populations.
Doping (semiconductors)Related: Doping shifts the Fermi level toward the conduction or valence band.
Fermi surfaceCompared with: It is an energy, whereas the Fermi surface is a set of momenta.
Work functionRelated: The work function measures the energy difference from this level to vacuum.
Electron–hole pairRelated: Its position helps determine how many electrons and holes are available.
Band theoryRelated: Its position relative to allowed bands indicates which states can carry current.
P-type semiconductorRelated: Acceptors shift the Fermi level toward the valence band.
