Electrical Engineering XYZ MCQs
What is the majority carriers of P type material:
- Protons
- Holes
- Electrons
- None of the above
Correct answer: 2. Holes
Explanation: In semiconductor physics, P-type materials are doped with acceptor impurities, which create an excess of “holes” in the crystal lattice. These holes effectively act as positive charge carriers. When a hole moves, it appears as if a positive charge is moving through the material. Therefore, holes are the majority carriers in P-type materials.
