First discovered in 2018, magic-angle graphene involves taking graphene—a single sheet of carbon atoms—and stacking two of those sheets on top of one another. The twist comes from the fact that the sheets are ever so slightly offset from one another, and this magic angle is what gives the graphene its really cool properties.
And the discovery of this twisted graphene started an entirely new field of study called twistronics, which explores how the structure of 2D materials influences their electronic behavior.
And now, the same researchers who twisted that magic angle into a graphene bilayer in the first place have mapped the entire structure of magic angle graphene for the first time using a technique called “scanning nano-SQUID.”
SQUID stands for Superconducting Quantum Interference Device.
