For germanium the forbidden energy gap is_______________?
Correct answer: D. 0.7eV
- A. 0.15 eV
- B. 0.25 eV
- C. 0.5eV
- D. 0.7eV
Explanation
Germanium has a forbidden energy gap of about 0.67 eV at room temperature, commonly rounded to 0.7 eV. Silicon, by comparison, has a larger gap of about 1.1 eV.
