The intrinsic semiconductor becomes an insulator at

A

`0^(@)C`

B

`-100^(@)C`

C

`300K`

D

`0 K`

Text Solution

Verified by Experts

The correct Answer is:
D
At `0K` temperature semiconductor behaves as an insulator, because at very low temperature electrons cannot jump from the valence band to conduction band.
