A few years ago, physicists were surprised to learn that stacking and subtly twisting two atomically thin layers of an electronic material like graphene creates a pattern that changes the material's properties and can even turn it into a superconductor. This superimposed grid, like what would emerge if two window screens were laid slightly askew, is called a moiré pattern.
