Layer graphene superconductivity is surprisingly strange

An illustration that represents the graphene of ultra -thin material Science/Alamy photo library Why do thin cold carbon sheets offer resistance to electric currents? Two experiments are bringing us closer to an answer, and perhaps even practical ambient superconductors. Kin Chung Fong At Northeastern University in Massachusetts, it was surprised when another physique, Abhishek Banerjee…
