Vedclass · Answer

(A) In an $N-$ type semiconductor,pentavalent impurity atoms are added to the intrinsic semiconductor. These atoms provide extra electrons for conduction. The energy level of these donor atoms,known as the donor energy level,lies just below the conduction band $(CB)$. This allows electrons to be easily excited into the conduction band at room temperature. Diagram $A$ correctly depicts the impurity energy level positioned just below the conduction band $(CB)$ and above the valence band $(VB)$.
