Practice question from Semiconductor Electronics (Class 12 · CBSE · Science Physics), with the correct answer and a step-by-step solution.
easy · MCQ · Q-5D05B2
At absolute zero temperature (), a silicon crystal acts as:
- A.A super-conductor
- B.An intrinsic semiconductor
- C.An insulatorCorrect answer
- D.A metallic conductor
Solution
At absolute zero temperature, all electrons in a semiconductor are tightly bound in covalent bonds and valence band is completely filled, while conduction band is empty. Thus, it acts as a perfect insulator.
