Researchers apply nanoscale graphene ‘magic’ angle to acoustics

Two atomically thin carbon sheets stacked on top of each other, called bilayer graphene, exhibit unique properties when one of the layers is twisted at a certain angle—a “magic” angle. The study of magic and other angle misalignments between two layers of material and their effects on material properties has been dubbed twistronics, a rapidly expanding field of condensed matter physics.
