Question:
In semiconductors, which of the following are true:
In semiconductors, which of the following are true:
Show Hint
Semiconductors behave differently with temperature; no conduction at 0 K.
Updated On: May 19, 2025
- No free electrons at 0K.
- No free electrons at any temperature.
- Free electrons increase with temperature.
- Less free electrons than conductor.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
At 0K, no free electrons ⇒ A is true.
At finite temperatures, thermal energy allows excitation ⇒ B is false.
More temperature ⇒ more conduction ⇒ C is true.
Fewer electrons than in metals ⇒ D is true.
