Question

An intrinsic semiconductor at \( T = 0 \, {K} \) behaves like

• A. insulator
• B. n-type semiconductor
• C. p-type semiconductor
• D. conductor
• E. superconductor

Hint:

At absolute zero, semiconductors behave like insulators due to the lack of free charge carriers.

Answer 1

The Correct Option is A

At absolute zero temperature \( T = 0 \, {K} \), all the electrons in an intrinsic semiconductor are in the valence band and there are no free electrons in the conduction band. 
Hence, it behaves like an insulator because no charge carriers are available for conduction. 
Thus, the correct answer is (A).
