MCQ
To get a $n-$type semiconductor from silicon, it should be doped with a substance with valence $......$
- A$2$
- B$1$
- C$3$
- ✓$5$
✓
Answer
Correct option: D.
$5$
Impurity of higher group is doped to get $n-$type semiconductor. Thus, silicon $($valency $= 4)$ should be doped with the element with valency equal to $5.$
