which of the following is true about the charge acquired by p- type semiconductors ?

Options

A. positive
B. neutral
C. negative
D. depends on concentration of p impurity

Answer

To determine the charge acquired by p-type semiconductors, we can analyze the characteristics of p-type semiconductors step by step.

### Step-by-Step Solution:

1. **Understanding P-Type Semiconductors**:
- P-type semiconductors are created when a semiconductor material, such as silicon, is doped with an element that has fewer valence electrons (typically three). Common dopants include boron.

2. **Charge Carriers in P-Type Semiconductors**:
- In p-type semiconductors, the doping creates "holes" which are essentially the absence of electrons. These holes can be thought of as positive charge carriers.

3. **Majority and Minority Carriers**:
- In p-type semiconductors, holes are the majority carriers, meaning they are present in greater numbers compared to electrons, which are the minority carriers.

4. **Net Charge of P-Type Semiconductors**:
- Despite the presence of holes (positive charge carriers), the overall charge of a p-type semiconductor remains neutral. This is because the number of positive holes is balanced by the number of negative electrons.

5. **Conclusion**:
- Therefore, the statement that best describes the charge acquired by p-type semiconductors is that they are neutral, meaning they do not acquire a net charge.

### Final Answer:
P-type semiconductors are neutral.
