NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the behavior of p-type and n-type semiconductors is correct?
A
In n-type semiconductors, electrons are the majority carriers, while holes are the minority carriers.
B
P-type semiconductors have excess electrons compared to holes due to trivalent doping.
C
In thermal equilibrium, n-type semiconductors have equal concentrations of holes and electrons.
D
P-type semiconductors are formed by doping with pentavalent impurities like phosphorus.
Correct Answer
Option A
Detailed Explanation
In n-type semiconductors, as stated in Chunk 2, electrons are indeed the majority carriers and holes are the minority carriers. P-type semiconductors, on the other hand, have holes as the majority carriers due to trivalent doping.
