A Columbia University-led team found a new method to induce superconductivity by finely tuning adjacent layers of graphene. They studied a sample with a twist angle of 1.3 degrees — the applied pressure transforms the material from a metal into either an insulator or a superconductor, through which an electric current can pass without resistance. This research provides new insight into the physics behind graphene’s lacy, honeycomb-like layers of carbon atoms.
