A transition characterized by a sudden change in electrical transport properties (conductivity)
due to a reversible change from localized to itinerant behaviour of the electrons.
Example: The transition at
in
VO2
where it changes from a high-temperature metallic behaviour to a low-temperature
semiconductor behaviour. Synonymous with metal–nonmetal transition.
