Preferred Label : Peierls transition;
IUPAC definition : A metal-insulator transition in quasi one-dimensional solids that occurs as a result
of a band gap opening up at the Fermi energy due to a displacive distortion of the
regular array increasing the unit cell length, usually a dimerization; the decrease
in electronic energy outweighs the increase in lattice energy. Example: The transition
in methylethylmorpholinium tetracyanoquinodimethanide at 335 K.;
