NEETChemistrySolid State
What is the characteristic feature of the band structure of semiconductors?
Options
- ALarge energy gap between the valence band and conduction band
- BNo energy gap between the valence band and conduction band
- CSmall energy gap between the valence band and conduction band
- DOverlapping of the valence band and conduction band
Correct answer
C. Small energy gap between the valence band and conduction band
Step-by-step solution
Semiconductors have a small energy gap between the valence band and conduction band, allowing some electrons to jump to the conduction band and exhibit conductivity.
