The majority charge carriers in a p type semiconductor are
- A. electrons
- B. holes
- C. protons
- D. neutrons
Explanation
Trivalent dopants create vacancies in the bonding structure, and these holes behave as mobile positive charges as neighbouring electrons shift to fill them. Electrons are still present as minority carriers, generated thermally. Protons and neutrons are locked in the nuclei and never move through the lattice.
