In a n-type semiconductor, which of the following statements is true? (a) Holes are minority carriers and pentavalent atoms are dopants. (b) Holes are majority carriers and trivalent atoms are dopants. (c) Electrons are majority carriers and trivalent atoms are dopants. (d) Electrons are minority carriers and pentavalent atoms are dopants.

Answer: (a). n-type is made by adding pentavalent (donor) atoms such as P, As, Sb. Donors give free electrons, so electrons are majority and holes are minority carriers. So the answer is (a).
