The majority charge carriers in a p type semiconductor are
Correct answer: B. holes
- 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.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
