What is the difference between n-type and p-type semiconductor?

Explanation

To understand the differences between n-type and p-type semiconductors, we can break down the information into several key points:

### Step-by-Step Solution:

1. **Definition of P-Type Semiconductor**:
- A p-type semiconductor is formed when a trivalent impurity (an element with three valence electrons) is added to a pure semiconductor (like silicon).
- Common trivalent impurities include boron, aluminum, and indium.
