Type: MCQ-fact-Hard-Class 12
What happens to the acceptor atoms in a p-type semiconductor at room temperature?
A
Most of the acceptor atoms get ionised, creating holes in the valence band.
B
All acceptor atoms remain neutral and do not contribute to conductivity.
C
Acceptor atoms gain electrons and become negatively charged.
D
The acceptor atoms repel holes, decreasing hole concentration.
Correct Answer
Option A
Detailed Explanation
At room temperature, most of the acceptor atoms in a p-type semiconductor become ionised, which results in the creation of holes in the valence band, as stated in the NCERT context.
