Study Tests, Controls Magic-Angle Twisted Bi-Layer Graphene Devices

If you stack two layers of graphene one on top of the other, and rotate them at an angle of 1.1º from each other - the so-called magic-angle, experiments have proven that the material can behave like an insulator, where no electrical current can flow, and at the same time can also behave like a superconductor, where electrical currents can flow without resistance.
