Graphene superconducting property discovered | KurzweilAI

Graphene superconducting property discovered | KurzweilAI: Scientists at... SLAC... have discovered how graphene... is superconducting in a graphene-calcium compound...

While it’s been known for nearly a decade that this combined material is superconducting, the new study offers the first compelling evidence that the graphene layers are instrumental in this process...

Researchers used a beam of intense ultraviolet light to look deep into the electronic structure of CaC6.

The purity of the sample combined with the high quality of the ultraviolet light beam allowed them to see deep into the material and distinguish what the electrons in each layer were doing, revealing details of their behavior that had not been seen before.
