In n-type semiconductor, free electrons donated by the impurity atoms occupy energy levels in (a) the conduction band. (b) the valence band. (c) the band gap and are close to the conduction band. (d) the band gap and are close to the valence band.

Answer: (c). The donor electron of a pentavalent impurity is loosely bound. Its level lies in the band gap, just below the conduction band. So the answer is (c).
