Vedclass · Answer

(A) In a $P$-type semiconductor,trivalent impurity atoms (like Boron,Indium,etc.) are added to the intrinsic semiconductor (like Silicon or Germanium).These impurity atoms create acceptor energy levels $E_A$ in the forbidden energy gap.These acceptor levels $E_A$ are located just above the valence band $E_V$ to facilitate the easy excitation of electrons from the valence band to the acceptor levels,thereby creating holes in the valence band.Therefore,the correct option is $A$.

In a $P$-type semiconductor,the acceptor energy levels $E_A$ are located:
