英英释义
Conduction band
The conduction band is the range of electron energies enough to free an electron from binding with its atom to move freely within the atomic lattice of the material as a 'delocalized electron'. Various materials may be classified by their band gap: this is defined as the difference between the valence and conduction bands.
