NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): In a semiconductor doped with a trivalent element, the majority charge carriers are holes. | Reason (R): Trivalent dopants in a semiconductor create vacancies or holes because they have one less valence electron than Si or Ge.
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 A
Detailed Explanation
When a trivalent dopant is added to Si or Ge, it creates a hole due to one less valence electron, making holes the majority charge carriers in p-type semiconductors.
