- A.Phosphorus
- B.Arsenic
- C.Boron
- D.Antimony
Show correct answer & step-by-step solution
Correct answer: C — Boron
Solution
To create a p-type semiconductor, a trivalent impurity must be added to a tetravalent semiconductor like silicon. Boron is a trivalent element, whereas phosphorus, arsenic, and antimony are pentavalent elements used for n-type doping.
