13. The impurity atoms with which silicon should be doped to make p-type semiconductors are A.Phosphorus B.Antimony C.Boron D.Germanium
Option C Solution: The impurity atoms with which pure silicon should be doped to make a p-type semiconductors are those of Boron and Aluminium that are trivalent in nature. So, they should be added in pure silicon to make p-type semiconductors.
