Concept explainers
Interpretation:
The electron population of energy bands of molecular orbital for given group
Concept introduction:
Valence band:
Valence band is defined as valence electron orbital of an element. It is a bunch of orbitals from which electrons shift to conduction band when excitation occurs. Conduction band and valence band are combined together in conductors. In semiconductors, there is a small band gap which separates conduction band and valence band.
Conduction band:
It is a bunch of orbitals into which electrons shift from valence band when excitation occurs. Electrons present in conduction band are free to move which creates
Band gap:
Band gap is the difference in energy between conduction band and valence band. In semiconductors, there is a small band gap which separates conduction band and valence band
