At T=0 K, the location of Fermi level with respect to the Ec and Ed for the n type material is?
Explanation: At T=0 K, the Fermi level of n band lies between the midway of Ec and Ed as intrinsic Fermi level always lies between the Ec and Ev.

What do you mean by the tem ‘FREEZE-OUT’?
Explanation: Freeze out means none of the electrons are transmitted to the conduction band.
