The technique for measuring the properties of this new twisted graphene is similarly low-tech. After a single layer of graphene is separated by sticky tape, the tape is torn in half to reveal two ...

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 ...

A well-studied example of this is graphene, a special form of ... Schneider is particularly interested in the optical properties of the twisted bilayers. For the experiments in the new project ...

"But by studying the electronic structure in the bilayer, we discovered that this material tends to "relax" into large, untwisted regions," Feraco explains. In technical terms, the twisted bilayer ...

The discovery of the new vortex electric field in the twisted bilayer has also created a 2D quasicrystal, potentially enhancing future electronic, magnetic and optical devices. Quasicrystals are ...
