Vedclass · Answer

(D) To form a $P$-type semiconductor,an intrinsic semiconductor like germanium $(Ge)$ is doped with trivalent impurity atoms.Boron $(B)$,Gallium $(Ga)$,and Aluminium $(Al)$ are all elements belonging to Group $13$ of the periodic table,meaning they have $3$ valence electrons.When these atoms are added to germanium,they create holes in the crystal lattice,which act as charge carriers,resulting in a $P$-type semiconductor.Therefore,all the given options are correct.

In a $P$-type semiconductor,germanium is doped with:
