Question:

For a p-type semiconductor, which of the following statements is true?

Electrons are the majority carriers and trivalent atoms are the dopants.

Holes are the majority carriers and trivalent atoms are the dopants.

Holes are the majority carriers and pentavalent atoms are the dopants.

Electrons are the majority carriers and pentavalent atoms are the dopants.

Solution:

Correct option is B. Holes are the majority carriers and trivalent atoms are the dopants. In p-type semiconductor, an intrinsic semiconductor is doped with trivalent impurities, that creates deficiencies of valence electrons called holes which are majority charge carriers. Hence option B is correct answer.
