What is the difference in the semi - conductors obtained by doping silicon with As or with Ga ?

Explanation

To understand the difference in the semiconductors obtained by doping silicon with arsenic (As) and gallium (Ga), we need to analyze the electronic configurations and the resulting charge carriers in each case.

### Step-by-Step Solution:

1. **Identify the Electronic Configuration**:
- Silicon (Si) has the electronic configuration of \( [Ne] 3s^2 3p^2 \), which means it has 4 valence electrons.
- Arsenic (As) has the electronic configuration of \( [Ar] 4s^2 4p^3 \), which means it has 5 valence electrons.
- Gallium (Ga) has the electronic configuration of \( [Ar] 4s^2 4p^1 \), which means it has 3 valence electrons.
