Abstract
We present a local growth algorithm for a decagonal quasicrystal. Using a three dimensional (3D) local growth rule, we grow a perfect Penrose tiling (PPT) layer on a growing decapod tiling layer. Once a PPT layer begins to form on the upper layer, successive 2D PPT layers can be added on top resulting in a perfect decagonal quasicrystal structure in bulk. Our growth rule implies that an ideal quasicrystal structure can be constructed by a local growth rule in 3D, contrary to the requirement of nonlocal information for a 2D PPT growth.
