NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram showing a silicon lattice doped with a trivalent element. Which of the following is the most likely effect of this doping on the semiconductor?
A
It creates holes, increasing the hole density in the valence band.
B
It creates electrons, increasing the electron density in the conduction band.
C
It decreases the intrinsic carrier concentration in the lattice.
D
It leads to the formation of n-type semiconductors by adding extra electrons.
Correct Answer
Option A
Detailed Explanation
When silicon is doped with a trivalent element, holes are created in the valence band, increasing the hole density, which is characteristic of p-type semiconductors.
