A material-keyboard made of graphene
Date Time A material-keyboard made of graphene Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side. 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 o...
