Room temperature intrinsic fermi level position). 7 variation of fermi level in intrinsic semiconductor. How many electrons make it to the conduction band at a given temperature? In an intrinsic semiconductor the fermi level is a hypothetical state which exists halfway between the bottom of the conduction band and the top of the valency band. if the two matetrials are brought into intimate contact, what would happen to the carriers and fermi level in these material? For an intrinsic semiconductor the fermi level is exactly at the mid of the forbidden band.energy band gap for silicon (ga) is 1.6v, germanium (ge) is 0.66v, gallium arsenide (gaas) 1.424v. Fermi level in an intrinsic semiconductor. This level has equal probability of occupancy for the the fermi energy for an intrinsic semiconductor is only undefined at absolute zero. Hence, using equation 4 and rearranging, the figure 1:
