Vanadium dioxide – a revolutionary material for future electronics industry

Geneva, Feb. 15 (xinhua) — vanadium dioxide is an ideal choice to replace silicon for a new generation of low-power electronic devices due to its unique properties. Swiss researchers have demonstrated the potential of using vanadium dioxide in aerospace communications (600677) systems to enable programmable radio frequency electronics. Vanadium dioxide has phase change characteristics, and its shape can be changed between insulator and metal. It is an insulator at room temperature and a metal conductor above 68 degrees Celsius. This [...]
