F (e) is the probability that a level with energy e will be filled by an electron, and the expression is:f (e) = 1 1. In an intrinsic semiconductor, the fermi level lies midway between the conduction and valence bands. We mentioned earlier that the fermi level lies within the forbidden gap, which basically results from the need to maintain equal concentrations of electrons (15) and (16) be equal at all temperatures, which yields the following expression for the position of the fermi level in an intrinsic semiconductor
