IISc research finds graphene electrons violate a fundamental law of Physics
Not only did the electrons in ultrapure graphene flow in a fluid state, they violated the Wiedemann-Franz law. As per the law, when electrical conductivity increases, thermal conductivity should also increase, and when one reduces the other should also reduce. But in ultrapure graphene, electrical and thermal conductivities shared an inverse relationship — as electrical conductivity increased, thermal conductivity decreased and vice versa
