NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about p-type and n-type semiconductors is correct?
A
Doping a semiconductor with a trivalent element creates holes in the valence band.
B
In p-type semiconductors, the majority carriers are electrons.
C
Pentavalent doping leads to a reduction in the hole concentration in the valence band.
D
At room temperature, n-type semiconductors have more holes than electrons.
Correct Answer
Option A
Detailed Explanation
Doping a semiconductor with a trivalent element, such as Boron, creates holes in the valence band as described in the context of p-type semiconductors. The other statements reflect common misconceptions about the majority carriers and the effects of doping.
