What is the advantage of heating a germanium semiconductor with silver or gold instead of indium or boron?

Explanation

To answer the question about the advantages of heating a germanium semiconductor with silver or gold instead of indium or boron, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Semiconductor Doping**:
- Doping is the process of adding impurities to a semiconductor to change its electrical properties. For germanium (Ge), which has four valence electrons, doping with elements that have three valence electrons (like indium or boron) creates a p-type semiconductor. This is because these elements create "holes" (electron deficiencies) in the semiconductor structure.

**Hint**: Remember that p-type semiconductors are formed by adding trivalent elements that create holes.
