Explain the difference between intrinsic semiconductors and extrinsic semiconductors.

Explanation

### Step-by-Step Solution:

1. **Definition of Intrinsic Semiconductors**:
- Intrinsic semiconductors are pure semiconductors without any significant dopant atoms present. They are characterized by their inherent electrical properties, which are solely determined by the semiconductor material itself.

2. **Definition of Extrinsic Semiconductors**:
- Extrinsic semiconductors are semiconductors that have been doped with impurities to enhance their electrical conductivity. The presence of these impurities introduces additional charge carriers (electrons or holes) into the material.
