Crystals have atoms that are arranged in a predictable, repetitive pattern. Materials called quasicrystals have atoms packed in ordered, but unexpected patterns. Now scientists have made a quasicrystal at the interface of two normal crystalline materials.

In new work, appearing October 10 in Nature, scientists layered a compound called perovskite barium titanate onto a crystal layer of platinum and watched as a thin-filmed, 12-atom, dodecagon-structured quasicrystal grew at the edge of the two...
