The energy gap between conduction band and the valence band of a substance is of the order of 0.07 eV. It is
The energy gap between conduction band and the valence band of a substance is of the order of 0.07 eV. It is
Right Answer is:
A Conductor
SOLUTION
The energy gap (= 0.07 eV) is so small that the valence band virtually touches the conduction band. Therefore, the substance is a conductor.
