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 state is 0 then no state should be there in semiconductor forbidden gap? So why we study of probability of occupancy of state in these conditions (semiconductor forbidden gap case).
3. How we calculate fermi level? Please suggest a very fundamental book; more basic than kittel
