Research finds surprising electron interaction in ‘magic-angle’ graphene

In 2018, physicists showed that something interesting happens when two sheets of the nanomaterial graphene are placed on top of each other. When one layer is rotated to a “magic angle” of around 1.1 degrees with respect to the other, the system becomes a superconductor—meaning it conducts electricity with zero resistance. Even more exciting, there was evidence that it was an unconventional form of superconductivity—a type that can happen at temperatures well above absolute zero, where most superconducting materials function.
