You’re probably familiar with moiré patterns, the large-scale interference patterns known in mathematics, physics, and art. They are created by overlaying one ruled opaque pattern with transparent gaps over another similar pattern. When they are rotated or displaced, the interference pattern appears.
Moiré patterns have shown to be especially useful with 2D-materials, single layer materials are lattices consisting of a single layer of atoms. Graphene, a single layer of atoms arranged in a two-dimensional honeycomb lattice nanostructure is one of the most well-known 2D-materials. When you take two stacked layers of graphene, twisted at the magic angle, all kinds of powerful properties can emerge such as superconductivity and ferromagnetism.
Now scientists have discovered a new range of composite materials they can design from moiré patterns with unique electrical and physical characteristics.
