Vedclass · Answer

(A) In a $P-$ type semiconductor,the material is doped with trivalent impurity atoms. This creates a large number of holes,which act as the majority charge carriers. Thermal excitation at room temperature generates a small number of free electrons,which act as the minority charge carriers. Therefore,a $P-$ type semiconductor has a large number of holes and few electrons.
