From the following, choose the element for impurity atoms with which pure silicon should be doped to make it a p-type semiconductor:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Boron
For a p-type semiconductor, silicon must be doped with a trivalent impurity (3 valence electrons).
And, among the given options, Boron is trivalent.
Answer: Boron
