Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): Doping a semiconductor with a pentavalent element results in an n-type semiconductor. | Reason (R): Pentavalent elements donate excess electrons that increase the number of charge carriers in the semiconductor.
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.
