Physicists have been riveted by systems composed of materials only one or a few layers of atoms thick. When a few sheets of these two-dimensional materials are stacked together, a geometric pattern called a moiré pattern can be formed. In these so-called moiré systems, new, exotic phenomena can occur, including superconductivity and unconventional magnetism. As a result, a better understanding of what happens at the interface between each sheet to cause these phenomena could lead to heady applications in novel electronics and much more. Now an international team of scientists…
