The majority charge carriers in `P`-type semiconductors are

Options

A. Electrons
B. Protons
C. Holes
D. neutrons

Explanation

To solve the question regarding the majority charge carriers in a P-type semiconductor, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding P-type Semiconductors**:
- A P-type semiconductor is formed by doping a pure semiconductor (like silicon) with a trivalent element (like boron).

2. **Doping with Trivalent Atoms**:
- Trivalent atoms have three valence electrons. When a trivalent atom is introduced into the silicon lattice, it replaces a silicon atom.

3. **Silicon Atom Valency**:
- Silicon has four valence electrons and forms four bonds with neighboring silicon atoms. When a boron atom (which has only three valence electrons) replaces a silicon atom, it forms only three bonds, leaving one bond incomplete.

4. **Formation of Holes**:
- The incomplete bond creates a "hole," which can be thought of as a positive charge carrier. This hole represents the absence of an electron where one would normally exist.

5. **Majority Charge Carriers**:
- In P-type semiconductors, these holes are the majority charge carriers because they are more abundant than the electrons (which are the minority carriers).

6. **Conclusion**:
- Therefore, the majority charge carriers in a P-type semiconductor are holes.

### Final Answer:
The majority charge carriers in P-type semiconductors are **holes**.
