Vedclass · Answer

(C) To obtain a $P$-type semiconductor,the intrinsic semiconductor (like Germanium or Silicon) must be doped with a trivalent impurity atom.Among the given options,Arsenic $(As)$,Antimony $(Sb)$,and Phosphorus $(P)$ are pentavalent elements (Group $15$),which are used to create $N$-type semiconductors.Indium $(In)$ is a trivalent element (Group $13$),which creates a deficiency of electrons (holes) when added to Germanium,thus forming a $P$-type semiconductor.Therefore,the correct option is $C$.

To obtain a $P$-type germanium semiconductor,it must be doped with
