What is doping why it is done

Explanation

### Step-by-Step Text Solution:

1. **Definition of Doping**:
Doping is the process of adding impurities to a pure semiconductor material, such as silicon or germanium, to modify its electrical properties.

2. **Purpose of Doping**:
The primary purpose of doping is to increase the conductivity of the semiconductor. Pure semiconductors have very low conductivity at room temperature (around 300 Kelvin). By adding specific impurities, we can enhance their ability to conduct electricity.
