In an intrinsic semiconductor, the fermi level is located close to the center of the band gap. A quasi fermi level (also called imref, which is fermi spelled backwards) is a term used in quantum mechanics and especially in solid state physics for the fermi level (chemical potential of electrons) that describes the population of electrons separately in the conduction band and valence band. A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. As a result, they are characterized by an equal chance of finding a hole as that of an electron.

A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. The fermi level starts to change location when temperature reaches 300k as a room temperature and fermi level will getting close to conduction band or valence band depending on energy band gap in semiconductor physics, the fermi energy would coincide with the valence band maximum. Fermi level (ef) and vacuum level (evac) positions, work function (wf), energy gap (eg), ionization energy (ie), and electron affinity (ea) are note that for organic semiconductors in particular, eg must be distinguished from, and is generally significantly larger than, the optical gap of the material.
