bilayer

If bilayer graphene is a playground for superconductivity, trilayer graphene appears to be the state fair.

Writing down a theory that fully captured the movement of unruly electrons in bilayer graphene was impossible, so the theorists started by imagining particles that were a bit better behaved.

In the months after the 2018 discovery, one group of theorists began to puzzle over the mechanism that made bilayer graphene superconduct.

“We had this zoo of different twisted materials, and twisted bilayer graphene was the only one that was clearly a superconductor,” Yankowitz said.
