Illustration of a moiré pattern that emerges upon stacking and rotating two sheets of bilayer graphene. Correlated electronic states with magnetic ordering emerge in twisted double bilayer graphene ...

That “Magic” angle, close to 1.1 degrees, flattened the electronic bands and amplified interactions so strongly that superconductivity and insulating states appeared in a material that, in its ...

(Nanowerk News) Superconducting materials are similar to the carpool lane in a congested interstate. Like commuters who ride together, electrons that pair up can bypass the regular traffic, moving ...

Superconductors are like the express trains in a metro system. Any electricity that "boards" a superconducting material can zip through it without stopping and losing energy along the way. As such, ...

Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move ...

Stacks of graphene, carefully twisted, gain a superpower: They become superconductors. Now scientists have new evidence that this “magic-angle” graphene is a member of a truly strange class of ...

That “magic” angle had long been suspected to be of special interest in twisted bilayer graphene. But no one had predicted it would be that interesting. “It would have been crazy to predict ...

In his theoretical model published in 2011, Canadian Allan MacDonald predicted that by twisting two graphene layers at a given angle, in the region of one degree, the interaction of electrons would ...

MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this ...

Physicists use a new platform to measure magic-angle graphene’s superconducting gap. The method involves “tunneling” electrons between two layers of magic-angle twisted tri-layer graphene (in yellow) ...
