Unusual Superconductivity Observed in Twisted Trilayer Graphene

July 08, 2022

The ability to turn superconductivity off and on with a literal flip of a switch in so-called "magic-angle twisted graphene" has allowed engineers to observe an unusual phenomenon that may shed new light on superconductivity in general. "While superconductors have been around for a long time, a remarkably new feature in twisted graphene bilayers and trilayers is that superconductivity in these materials can be turned on simply through the application of a voltage on a nearby electrode," says Stevan Nadj-Perge, Assistant Professor of Applied Physics and Materials Science.
