At absolute zero temperature, semiconductor behaves as a/an:
Updated On: Jul 12, 2022
- dielectric
- conductor
- insulator
- super conductor
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The semiconductor behaves as an insulator at absolute zero temperature because at absolute zero temperature, the conduction band becomes empty and valence band becomes completely filled. The forbidden gap between conduction band and valence band is very small, which has the value of only 1 eV therefore, electrons cannot jump from valence band to conduction band.

Concepts Used:
Semiconductors
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
Properties of Semiconductor:
- Semiconductor acts like an insulator at Zero Kelvin. On increasing the temperature, it works as a conductor.
- Due to their exceptional electrical properties, semiconductors can be modified by doping to make semiconductor devices suitable for energy conversion, switches, and amplifiers.
- Lesser power losses.
Uses of Semiconductor:
- Semiconductors are widely used in manufacturing electronics devices like transistors, diodes, sensors, integrated circuits.
- Semiconductors are widely used in all electronic devices, like mobile phones, digital cameras, communication devices, trains, ATMs, etc.
