under the influence of electric field , which of the following statement is true about the movement of electrons and holes in p- type semiconducter ?

Options

A. Electron will move towards the positvely charged plate through electron holes
B. Holes will appear to be moving towards the negatively charged plate
C. Both electrons and holes appear to move towards the positively charged plate
D. Movement of electrons is not related to the movement of holes.

Explanation

To solve the question regarding the movement of electrons and holes in a p-type semiconductor under the influence of an electric field, we can break down the concepts step by step.

### Step-by-Step Solution:

1. **Understanding p-type Semiconductors**:
- A p-type semiconductor is formed when a pure semiconductor (like silicon) is doped with a trivalent impurity (like aluminum). This creates "holes" or deficiencies in electrons.

2. **Behavior of Electrons and Holes**:
- In a p-type semiconductor, the majority charge carriers are holes (positive charge), while electrons are the minority carriers.
- When an electric field is applied, the behavior of these charge carriers changes based on their charge.

3. **Movement of Electrons**:
- Electrons have a negative charge and will move towards the positively charged plate when an electric field is applied. This is due to the attraction between opposite charges.

4. **Movement of Holes**:
- Holes can be thought of as positive charge carriers. They will move towards the negatively charged plate because they are attracted to the negative charge.

5. **Analyzing the Options**:
- **Option A**: "Electrons will move towards the positively charged plate through electron holes." - This statement is true because electrons indeed move towards the positive plate.
- **Option B**: "Holes will appear to be moving towards the negatively charged plate." - This statement is also true as holes move towards the negative plate.
- **Option C**: "Both electrons and holes appear to move towards the positively charged plate." - This statement is false because holes move towards the negative plate.
- **Option D**: "Movement of electrons is not related to the movement of holes." - This statement is also false as the movement of holes and electrons is interconnected in a semiconductor.

6. **Conclusion**:
- The correct statements are Option A and Option B. Therefore, the answer to the question is that both electrons move towards the positively charged plate and holes move towards the negatively charged plate.

### Final Answer:
- **Correct Options**: A and B.
