Type: MCQ-fact-Medium-Class 12
What happens to an intrinsic semiconductor at a temperature above absolute zero?
A
It behaves like a conductor due to thermally excited electrons.
B
It remains an insulator with no charge carriers.
C
It becomes a superconductor at high temperatures.
D
It only conducts electricity under very high voltages.
Correct Answer
Option A
Detailed Explanation
At temperatures above 0 K, thermal energy excites some electrons from the valence band to the conduction band, enabling the semiconductor to conduct electricity.
