Graphene just broke a fundamental law of physics.Its electrons just did something physicists thought was impossible. For nearly 200 years, metals have obeyed the Wiedemann-Franz law – the rule that electrical conductivity and thermal conductivity always rise and fall together. But in ultra-clean graphene, researchers at the Indian Institute of Science found the opposite. As electrical conductivity...
