Rotating carbon layers can turn them into superconductors
By twisting two sheets of graphene to a specific magic angle, physicists can fundamentally change how electricity flows through the material.
Graphene is a single layer of carbon atoms arranged in a honeycomb lattice. While it is naturally a highly conductive material, researchers discovered that its electronic properties are not fixed by its chemical makeup. Instead, they can be manipulated through a geometric technique called twistronics. By stacking two layers of graphene and rotating them against each other, the material's behavior shifts dramatically based on the degree of the twist.
