Hydrothermal preparation of vanadium dioxide thin films and research progress of terahertz modulation

Vanadium dioxide is a functional material with thermotropic properties. The phase transition temperature is close to room temperature, and the metal-insulator transition at the phase transition temperature is accompanied by the abrupt change of light and electrical properties. It has important research value and Potential application prospects. In this paper, the research status and improvement methods of the preparation of vanadium dioxide thin films by hydrothermal method are reviewed, and the research progress of the modulation characteristics of vanadium dioxide thin terahertz in recent years is reviewed, and the future development trend is put forward.
