NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about p-type semiconductors is correct?
A
The acceptor energy level is above the valence band and ionizes at room temperature.
B
Holes in p-type semiconductors are created by the addition of electrons.
C
Doping with trivalent atoms decreases the density of holes in the valence band.
D
The majority carriers in p-type semiconductors are electrons.
Correct Answer
Option A
Detailed Explanation
Statement A is correct as the acceptor energy level is indeed slightly above the top of the valence band, allowing for ionization at room temperature, which creates holes. Other options misrepresent the role of holes and carriers in p-type semiconductors.
