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.
