Meaning and Definition
A specific energy band in a solid material where electrons can move freely, enabling the flow of electric current.
In solid-state physics, the conduction band is the range of electron energy levels where electrons are not bound to individual atoms and are free to move, carrying electrical charge. It sits above the valence band, and the gap between them (the band gap) determines whether a material is a conductor, semiconductor, or insulator.

FAQ
Frequently Asked Questions
No, it is a highly specialised term exclusive to physics and engineering contexts.
The valence band contains bound electrons, while the conduction band contains free, mobile electrons that can carry current.
No, it is exclusively a compound noun. There is no verb form 'to conduction band'.
Yes, in the band theory of solids, all materials have conduction and valence bands, but their relative energies and the gap between them determine the material's electrical properties.
A specific energy band in a solid material where electrons can move freely, enabling the flow of electric current.
Conduction band is usually technical / scientific in register.
Conduction band: in British English it is pronounced /kənˈdʌkʃn̩ bænd/, and in American English it is pronounced /kənˈdʌkʃ(ə)n bænd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a CONDUCTION band as a CONDUIT or highway where electrons can freely travel to conduct electricity.
Conceptual Metaphor
Often visualised as an empty highway above a full parking lot (valence band); electrons need enough energy to jump from the lot onto the highway to move freely.
