The energy gap between conductionband and valence band is of the order of 0.07 eV. It is a/an

A

insulator

B

conductor

C

semiconductor

D

alloy

Text Solution

Verified by Experts

The correct Answer is:
C

The energy gap between conduction band and valence bannd is 0.07 eV, which is very small. So, the electrons very easily go from valency band to conduction band by gaining the little energy. Hence, the material is a conductor.
