Options

A. a bond is broken on the n-side and the electron freed from the bond jumps to the conduction band
B. a conduction electron on the p-side jumps to a broken bond to complete it
C. a bond is broken on the n-side and the electron freed from the bond jumps to a broken bond on the p-side complete it.
D. a bond is broken on the p-side and the electron freed from the bond jumps to a broken bond on the n-side to complete it.

Answer

To solve the question, "A hole diffuses from the p-side to the n-side in a p-n junction. This means that," we can break it down into a series of logical steps:

### Step-by-Step Solution:

1. **Understanding the P-N Junction**:
- A p-n junction consists of two types of semiconductor materials: p-type (which has an abundance of holes) and n-type (which has an abundance of electrons).

2. **Definition of a Hole**:
- A hole is defined as the absence of an electron in a semiconductor. It behaves as a positive charge carrier.

3. **Diffusion Process**:
- When we say a hole diffuses from the p-side to the n-side, it means that the hole is moving from an area of higher concentration (p-side) to an area of lower concentration (n-side).

4. **Electron Movement**:
- As the hole moves from the p-side to the n-side, it creates a vacancy (or a hole) in the p-side. This movement of the hole implies that an electron from the n-side must move to the p-side to fill this vacancy.

5. **Bond Breakage**:
- When an electron moves from the n-side to the p-side, it breaks a bond in the n-side. This bond breakage allows the electron to move freely.

6. **Recombination**:
- The electron that has moved to the p-side can recombine with the hole, effectively completing the bond that was broken.

7. **Conclusion**:
- Therefore, the process of a hole diffusing from the p-side to the n-side results in the breaking of a bond on the n-side and the movement of an electron from the n-side to the p-side to fill the hole.

### Final Answer:
A hole diffusing from the p-side to the n-side means that a bond is broken on the n-side, and the electron freed from that bond jumps to the p-side to complete the bond with the hole.
