Question

What is gap between valence band and conduction band called?
all the above
forbidden band gap
energy gap
band gap

Answer 1

Answer:

insulators, the forbidden energy gap is largest and it is of the order of 6 eV. Explanation: In insulators, the forbidden energy gap is very large, in the case of semiconductor it is moderate and in conductors, the energy gap is zero.

Answer 2

Answer:

It is called as forbidden zone..............
