NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): An intrinsic semiconductor will behave like an insulator at T = 0 K. | Reason (R): The energy band gap in an intrinsic semiconductor is zero at T = 0 K.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option C
Detailed Explanation
While the assertion is true that an intrinsic semiconductor behaves like an insulator at T = 0 K due to the absence of thermally excited electrons, the reason is incorrect because the energy band gap is not zero at T = 0 K.
