Question

In a n-type semiconductor, which of the following statements is true?

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

Answer 1

The correct option is C Holes are minority carriers and pentavalent atoms are dopants.

The n-type semiconductor can be produced by doping impurity atoms of valence 5 i.e, pentavalent atoms like phosphorous and so electrons are majority charge carriers and Holes are minority charge carriers.

So correct answer is option C.
