A p-type material is electrically...

Options

A. positive
B. negative
C. neutral
D. depends upon the concentration of p impurities

Explanation

To solve the question "A p-type material is electrically...", we need to analyze the characteristics of p-type materials in semiconductor physics.

### Step-by-Step Solution:

1. **Understanding p-type Materials**:
- P-type materials are semiconductors that are doped with acceptor impurities. These impurities create "holes" in the semiconductor's crystal lattice, which are essentially the absence of electrons.

2. **Charge Carriers in p-type Materials**:
- In p-type semiconductors, the majority charge carriers are holes, which can be thought of as positive charge carriers. This is because holes can move through the lattice and carry a positive charge.

3. **Fixed Acceptor Atoms**:
- The dopant atoms (acceptors) that are introduced into the semiconductor lattice to create p-type material have a tendency to accept electrons. This means that while the holes (positive charge carriers) are present, there are also fixed acceptor atoms that are negatively charged due to the presence of unfilled electron states.

4. **Overall Charge of p-type Material**:
- While p-type materials have positive charge carriers (holes), they also contain negatively charged acceptor atoms. The overall charge of the material can be considered neutral because the positive and negative charges balance each other out.

5. **Conclusion**:
- Therefore, when we say "A p-type material is electrically...", the correct answer is that it is electrically neutral.

### Final Answer:
A p-type material is electrically neutral.
