It can be shown for intrinsic semiconductors that fermi energy level  lies midway between conduction band and valence band. The proof is as follows:

At any temperature (T>0K)

ne = number of electrons in conduction band

nv = number of electrons in valence band

We have, by definition of intrinsic …
