45. The intrinsic semiconductor becomes an insulator at
[2001]
(a) $0^{\circ} C$
(b) $0 $ $K$
(c) $300$ $ K$
(d) $-100^{\circ} C$
Show Answer
Answer:
Correct Answer: 45.(b)
Solution:
- (b) At $0 $ $K$, motion of free electrons stop. Hence conductivity becomes zero. Therefore, at $0 $ $K$ intrinsic semiconductor becomes insulator.
