Vedclass · Answer

(D) At absolute zero temperature $(T = 0 \ K)$, all the valence electrons are tightly bound to their respective atoms in the crystal lattice.There is no thermal energy available to excite electrons from the valence band to the conduction band.Consequently, the conduction band remains completely empty, and the valence band is completely filled.Due to the absence of free charge carriers, the semiconductor acts as a perfect insulator.

At absolute zero temperature, a semiconductor behaves like
