The forbidden energy gap for Si is
- A 1.1 eV
- B 0.7 eV
- C 3.0 eV
- D 5.4 eV
Answer & Solution
Correct Answer
(A) 1.1 eV
Step-by-step Solution
Detailed explanation
Silicon (Si): At room temperature (300 K), the gap is approximately 1.1 eV. Germanium (Ge): Has a smaller gap of about 0.7 eV (Option B). Diamond: An insulator with a much larger gap of about 5.4 eV (Option D). A) 1.1 eV
