Question

precise definition of Conduction Band

Answer 1

Conduction Band

The set of electron orbitals, generally the outermost shells of the atoms in a conductor or semiconductor, in which electrons are free to move and thereby carry an electric current.

Answer 2

In non-metals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states.
