Definitions from the Web
Term: Bandgap
Definition: The energy difference between the valence band and the conduction band in a solid material, which determines its electrical conductivity.
Parts of Speech: noun
Senses:
- The energy difference between the valence band and the conduction band in a solid material.
Usages:
