Question

n-type silicon is obtained by doping silicon with
(A) Germanium (B) Aluminium
(C) Boron (D) Phosphorus

Answer 1

phosphorus will be right answer

Answer 2

Answer:

The correct answer would be the

option (D)Phospherous

Explanation:

N-type silicon is silicon that has been chemically combined (doped) with phosphorus gas to make it conductive. A silicon atom has four electrons in its outer shell and bonds tightly with four surrounding silicon atoms creating a crystal matrix with eight electrons in the outer shells. However, phosphorus has five electrons, and when combined, the fifth electron becomes a "free" electron that moves easily within the crystal when a voltage is applied. Because the charge carriers are electrons, n-type refers to a negative charge.

Therefore according to me,The correct anwer would be option (D) Phospherous
