[" Packing maction of a nucteus is themi level lies in the energy gap,"],[" band."]

In.............semiconductor, the fermi level lies in the energy gap, very close to valence band.

In.............semiconductor, the fermi level lies in the energy gap, very close to conduction band.

Distinguish between energy levels and energy bands.

Assertion : The electrons in the conduction band have higher energy than those in the valence band of a semiconductor Reason : The conduction band lies above the energy gap and valence band lies below the energy gap.
