Insulator–metal transition in VO2 film on sapphire studied by broadband dielectric spectroscopy

Insulator–metal transition in VO2 film on sapphire studied by broadband dielectric spectroscopy

Abstract Vanadium dioxide ( $$\hbox {VO}_2$$ ) is a favorable material platform of modern optoelectronics, since it manifests the reversible temperature-induced insulator-metal transition (IMT) with an abrupt and rapid changes in the conductivity and optical properties. It makes possible application...
