"This material could be used to help stabilize temperature," said researcher Fan Yang.Researchers have discovered a metal that fails to comply with the Wiedemann-Franz Law, the rule that suggests good conductors of electricity will also be good conductors of thermal energy. Metallic vanadium dioxide easily carries an electric current, but fails to conduct heat as expected. "This was a totally unexpected finding," Junqiao Wu, a professor of materials science and engineering at the University of California, Berkeley, said in a news release. "It shows a drastic breakdown of a textbook law that has been known to be robust for conventional...
