- C.
- D.
Show correct answer & step-by-step solution
Correct answer: A —
Solution
- Semiconductors are materials with an intermediate electrical conductivity between conductors and insulators.
- The electrical properties of a semiconductor are determined by the forbidden energy gap between the valence band and the conduction band.
- For typical semiconductors like silicon or germanium, this energy gap is approximately .
- Hence the answer is (A).
