A Breakthrough in Nanotechnology: A Material-Keyboard Made of Graphene
The material keyboard realized by the ETH Zurich researchers. By applying electric voltages (“keys”) at different points, the magic-angle graphene can become locally superconducting (electron pairs) or isolating (barrier on the right).
