Value of forbidden energy gap for semi conductor is:

Options

A. 1 eV
B. 6 eV
C. 0 eV
D. 3 eV

Explanation

To solve the question regarding the value of the forbidden energy gap for semiconductors, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Forbidden Energy Gap**:
- The forbidden energy gap (also known as the band gap) is the energy difference between the conduction band and the valence band in a semiconductor. It determines the electrical conductivity of the material.

2. **Identify the Energy Bands**:
- In a semiconductor, the conduction band is the range of energy levels that electrons can occupy when they are free to move and conduct electricity. The valence band is the range of energy levels that electrons occupy when they are bound to atoms and not free to move.

3. **Determine the Value for Semiconductors**:
- For semiconductors, the typical value of the forbidden energy gap (Eg) is approximately 1 electron volt (eV). This value can vary slightly depending on the specific type of semiconductor material, but 1 eV is a standard reference.

4. **Select the Correct Answer**:
- Given the options, the correct answer for the value of the forbidden energy gap for semiconductors is **1 electron volt (1 eV)**.

### Final Answer:
The value of the forbidden energy gap for semiconductors is **1 electron volt (1 eV)**.
