The VO2 film undergoes a reversible phase transition from a semiconductor state to a metallic state at 68°C. This thermally induced phase change characteristic allows the VO2 film to be widely used in smart window materials, switching devices and other fields, but the higher phase transition temperature (68°C ), still limits its practical application.
Doping tungsten can significantly reduce the phase change temperature of VO2, so that the temperature at which it changes from a high-temperature phase (metallic phase) to a low-temperature phase (insulating phase) reaches room temperature or close to room temperature. The adjustment of this phase change temperature is tungsten-doped vanadium dioxide. Applications near room temperature are possible.
