Aperiodic approximants for relating quasicrystals and modulated structures - EurekAlert
By constructing hexagonal metallic-mean approximants of the honeycomb lattice, scientists from Tokyo Tech, Nagoya University, Toyota RIKEN, and Kindai University have linked incommensurately modulated structures and quasicrystals, two classes of aperiodic crystals. They found that a quasicrystal converges to a modulated honeycomb crystal on arranging tiles based on metallic means. This metallic-mean tiling pattern was also identified in polymer and colloidal systems in soft-matter self-assemblies, providing new insights into aperiodic crystals.
