metal–insulator transition

Synonym: metal–nonmetal transition
https://doi.org/10.1351/goldbook.M03863
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 \(339\ \text{K}\) in VO2 where it changes from a high-temperature metallic behaviour to a low-temperature @S05591@ behaviour. Synonymous with metal–nonmetal transition.
