A five-dimensional model of dodecagonal Ta-Te quasicrystals with fractal occupation domains

A five-dimensional model of dodecagonal Ta-Te quasicrystals with fractal occupation domains The consideration of two approximants of the first stable dodecagonal Ta-Te quasicrystal shows that the five-dimensional (5D) space group of the dodecagonal phase is and the structure consists of five layers within a 10 A period. A 5D quasicrystal model leading to the two approximant structures by the introduction of appropriate linear phason strains is derived by the section method. The model shows 20 A dodecagonal clusters (DDC) arranged at each vertex of the square-triangle dodecagonal pattern and has fractal occupation domains, suggesting that the quasicrystal has either a deterministic or a random square-triangle packing of the DDC. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section A: Foundations of Crystallography International Union of Crystallography
