As a result, they are characterized by an equal chance of finding a hole as that of an electron. Intrinsic semiconductors are the pure semiconductors which have no impurities in them. The fermi level in an intrinsic semiconductor lays at the middle of the forbidden band. For a pure intrinsic semiconductor in which the chemical potential lies at the exact middle of the gap, the activation energy should correspond to half of the value of the gap. We can find the intrinsic fermi level and simplify the results somewhat: Fermi level (ef) and vacuum level (evac) positions, work function (wf), energy gap (eg), ionization energy (ie), and electron affinity (ea) are parameters of great note that for organic semiconductors in particular, eg must be distinguished from, and is generally significantly larger than, the optical gap.
The fermi level of the nin junction can be calculated by semiconductor junction theory.
Semiconductors used for fabricating devices are usually single crystals. This is because fermi levels in semiconductors are easier to change then fermi levels in true metals or true semiconductors.
