In 2018, a group of researchers at the Massachusetts Institute of Technology (MIT) pulled off a dazzling materials science magic trick. They stacked two microscopic cards of graphenesheets of carbon one atom thickand twisted one ever so slightly. Applying an electric field transformed the stack from a conductor to an insulator and then, suddenly, into a superconductor:…
