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

Answer: (c). n-type: pentavalent dopant gives extra electrons, so electrons are majority carriers. Holes are then minority carriers. So the answer is (c).
