In an n type silicon, which of the following statements is true:

Options

A. Electrons are majority carriers and trivalent atoms are the dopants.
B. Electrons are minority carriers and pentavalent atoms are the dopants.
C. Holes are minority carriers and pentavalent atoms are the dopants.
D. Holes are majority carriers and trivalent atoms are the dopants.

Answer

C

Explanation

Holes are minority carriers and pentavalent atoms are the dopants.
An n-type silicon is obtained when pentavalent atoms, such as phosphorus are doped in silicon atom hence in an n-type silicon, the electron are the majority carrier, while the holes are the minority carriers.
