1. Fermi level is also defined as highest energy level at which electron can exist at 0K then it should be top of valence band but why is it in between conduction band and valence band ( in forbidden gap)? It should be in conduction band or valence band. How to explain this?
2. If density of...
Thanks for clearing my doubts. But I have got more doubts. Hope you will help me clear my doubts.
1. If density of state is 0 then no state should be there. So why we study of probability of occupancy of state in these conditions (semiconductor forbidden gap case).
2. Fermi level is also...

According to Fermi Distribution function the probability of finding electron at fermi level is 1/2.
In intrinsic semiconductor fermi level lies in forbidden gap where no electron can exist. So probability should be 0.
Pleaze explain me the concept and remove the ambiguity!
