Question

energy gap between valence band and conduction band of semiconductor is
1:- 0
2:- infinity
3:- 1ev
4:- 10ev

Answer 1

energy gap between valence band and conduction band of semiconductor is 10 ev

Answer 2

it is 1 ev there is a gap between valency and conduction band not more than insulators it's exact value is 1.1 ev option 3 is answer
