NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): At room temperature, the density of holes in the valence band of a p-type semiconductor is predominantly due to impurity. | Reason (R): The acceptor energy level in a p-type semiconductor is slightly above the top of the valence band, allowing electrons to easily jump and ionise the acceptor atoms.
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 but R is true.
Correct Answer
Option A
Detailed Explanation
The assertion and reason are both true and linked; the acceptor energy level being just above the valence band facilitates ionisation, leading to holes due to impurity.
