To get a n-type semiconductor from silicon, it should be doped with a substance with valence__________.
(i) 2
(ii) 1
(iii) 3
(iv) 5
Answers (1)
The answer is the option (iv) 5.
To get n-type semiconductor impurity of higher group is doped. Thus, to get a n-type semiconductor, silicon (valency = 4) should be doped with the element with valency equal to 5.
