Vedclass · Answer

(A) In a $P$-type semiconductor,trivalent impurity atoms (like Boron,Aluminum,etc.) are added to the intrinsic semiconductor (like Silicon or Germanium).These impurity atoms create an additional energy level in the forbidden energy gap,just above the valence band.Since these atoms accept electrons from the valence band to create holes,this energy level is known as the Acceptor energy level,denoted by $E_A$.

In a $P$-type semiconductor,the energy level formed in the forbidden gap near the valence band is called ...
