Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about intrinsic semiconductors is correct?
A
At absolute zero, intrinsic semiconductors behave like insulators.
B
Thermal energy at higher temperatures does not affect electron excitation in intrinsic semiconductors.
C
Intrinsic semiconductors have an equal number of electrons in the conduction band and holes in the valence band at all temperatures.
D
Intrinsic semiconductors can conduct electricity at absolute zero.
Correct Answer
Option A
Detailed Explanation
At absolute zero, intrinsic semiconductors behave like insulators as no electrons are thermally excited into the conduction band. This is supported by the description of intrinsic semiconductors in the provided context.
