Vedclass · Answer

(C) At absolute zero temperature $(T = 0 \ K)$,there is no thermal energy available to excite electrons from the valence band to the conduction band in a pure semiconductor like silicon.Consequently,the valence band is completely filled and the conduction band is completely empty.Due to the absence of free charge carriers,the material cannot conduct electricity.Therefore,pure silicon behaves as an insulator at absolute zero temperature.
