What are the majority charge carriers in P-type semiconductor material?
- A Free protons
- B Free neutrons
- C Holes
- D Free electrons
Correct answer: C — Holes. From the official ISED question bank, verified word for word.
Why
In P-type semiconductor material, the manufacturing process adds impurities that create a shortage of electrons, leaving behind empty spaces called holes. The full explanation — and one for every question — is in Pro.
