NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a diagram where a semiconductor wafer has a thin p-type region and a small part of it is converted into an n-type region by adding a pentavalent impurity. What is formed at the interface of these two regions?
A
p-n junction
B
zener diode
C
half-wave rectifier
D
n-p junction
Correct Answer
Option A
Detailed Explanation
When a small quantity of pentavalent impurity is added to a p-type silicon wafer, a p-n junction is formed at the interface of the p-type and n-type regions.
