Preferred Label : valence band;
IUPAC definition : Highest energy continuum of energy levels in a solid that is fully occupied by electrons
at 0 K.;
Scope note : sample characterized by a (unique) sample axis z with all directions perpendicular
to z being equivalent. in other words, the sample properties are invariant to rotation
around z. uniaxiality exists in many anisotropic samples and simplifies the interpretation
of their spectra considerably.; in metals the valence band is the conduction band.; the valence band is lower in energy than the conduction band and is generally completely
full in semiconductors. when heated, electrons from the valence band jump out of the
band across the band gap and into the conduction band, making the material conductive.
the fermi level separates the valence band from the conduction band.;
