In terms of energy band, semiconductor materials at room temperature do NOT have
Correct answer: A. partially filled valence band.
- A. partially filled valence band.
- B. partially filled conduction band
- C. plenty of free electrons for electrical conduction
- D. narrow forbidden energy gap between conduction and valence band
Explanation
Semiconductor materials at room temperature do not have a partially filled conduction band, as this would indicate metallic behavior. The correct answer is that they have a partially filled valence band, which is essential for their conductivity. The other options are incorrect because semiconductor materials do not have a narrow forbidden energy gap like insulators, nor do they have plenty of free electrons like metals.
