Abstract
Vanadium dioxide (VO(2)) is a typical metal-insulator transition (MIT) material, which changes from room-temperature monoclinic insulating phase to high-temperature rutile metallic phase. The phase transition of VO(2) is accompanied by sudden changes in conductance and optical transmittance. Due to the excellent phase transition characteristics of VO(2), it has been widely studied in the applications of electric and optical devices, smart windows, sensors, actuators, etc. In this review, we provide a summary about several phases of VO(2) and their corresponding structural features, the typical fabrication methods of VO(2) nanostructures (e.g., thin film and low-dimensional structures (LDSs)) and the properties and related applications of VO(2). In addition, the challenges and opportunities for VO(2) in future studies and applications are also discussed.
