A intrinsic semiconductor at a absolute ...

A intrinsic semiconductor at a absolute zero of temperature behaves as

A

conductor

B

p-type semiconductor

C

n-type semiconductor

D

insulator

Text Solution

Verified by Experts

The correct Answer is:
D
At 0 K there is no free electrons for conduction.
Therefore, at 0 K an intrinsic semiconductor behaves as an insulator.
