NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a diagram showing two types of semiconductors: one doped with a pentavalent impurity and the other with a trivalent impurity. Which of the following correctly identifies the majority carriers in each semiconductor?
A
Electrons in n-type, holes in p-type
B
Holes in n-type, electrons in p-type
C
Electrons in both n-type and p-type
D
Holes in both n-type and p-type
Correct Answer
Option A
Detailed Explanation
In an n-type semiconductor, electrons are the majority carriers due to doping with a pentavalent impurity. In a p-type semiconductor, holes are the majority carriers due to doping with a trivalent impurity.
