The barrier voltage at a pn junction for germanium is about________________?
Correct answer: D. 0.3 V
- A. 5 V
- B. 3 V
- C. Zero
- D. 0.3 V
Explanation
The barrier voltage of a silicon junction is about 0.7 V, while germanium has the lower value of approximately 0.3 V. The other voltage values are not normal pn-junction barrier potentials.
