Silicon can be doped to get an n-type semiconductor by using :
(A) Arsenic (As)
(B) Phosphorus (P)
(C) Boron (B)
(D) Antimony (Sb)
- A (A) and (C) only
- B (B) and (C) only
- C (A), (B) and (D)
- D (C) and (D) only
Answer & Solution
Correct Answer
(C) (A), (B) and (D)
Step-by-step Solution
Detailed explanation
Elements from Group 15 (pentavalent impurities) are used to dope Silicon for an n-type semiconductor. Arsenic (As), Phosphorus (P), and Antimony (Sb) are Group 15 elements. Boron (B) is a Group 13 element (trivalent impurity) used for p-type semiconductors. Therefore, (A), (B),…
