Write the relation between number density of holes and number density of free electrons in an intrinsic semiconductor

Explanation

To derive the relation between the number density of holes (p) and the number density of free electrons (n) in an intrinsic semiconductor, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Intrinsic Semiconductors**:
- An intrinsic semiconductor, such as silicon, has a perfectly balanced number of free electrons and holes. In intrinsic semiconductors, the conduction of electricity occurs due to the movement of both electrons and holes.

2. **Covalent Bonding in Silicon**:
...
