Aperiodic crystals are crystals that lack three-dimensional translational symmetry, but still exhibit three-dimensional long-range order.[1] In other words, they are periodic crystals in higher dimensions.[clarification needed] They are classified into three different categories: incommensurate modulated structures, incommensurate composite structures, and quasicrystals.[2]
