Vanadium dioxide (VO2) is a transition metal oxide semiconductor that exhibits a dramatic metal-insulator transition (MIT) near room temperature, shifting from insulating monoclinic to conducting tetragonal crystal structure. This phase-change behavior makes it valuable for smart windows and thermal management coatings that dynamically respond to temperature, as well as emerging applications in reconfigurable electronics and infrared optics where its optical and electrical properties can be reversibly switched. While primarily in research and early commercialization phases, VO2 offers a platform for functional materials where passive thermal response or electronically-tuned properties provide advantages over static alternatives.
