Question:
In a pure semiconductor at thermal equilibrium
In a pure semiconductor at thermal equilibrium
Show Hint
In an intrinsic semiconductor:
\[
n=p
\]
Electrons and holes are always produced in equal numbers.
Updated On: Apr 27, 2026
- Number of electrons \(>\) number of holes
- Number of electrons \(=\) number of holes
- Number of holes \(>\) number of electrons
- Only electrons are charge carriers
- Only holes are charge carriers
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In a pure or intrinsic semiconductor, electrons and holes are generated in pairs.
So at thermal equilibrium:
\[
n=p
\]
where:
\[
n = \text{electron concentration},\qquad p = \text{hole concentration}
\]
Therefore, the number of electrons equals the number of holes.
Hence, the correct answer is: \[ \boxed{(B)\ \text{Number of electrons = Number of holes}} \]
Hence, the correct answer is: \[ \boxed{(B)\ \text{Number of electrons = Number of holes}} \]
