Self-assembly of a space-tessellating structure in the binary system of hard tetrahedra and octahedra

Author affiliations

Abstract

We report the formation of a binary crystal of hard polyhedra due solely to entropic forces. Although the alternating arrangement of octahedra and tetrahedra is a known space-tessellation, it had not previously been observed in self-assembly simulations. Both known one-component phases – the dodecagonal quasicrystal of tetrahedra and the densest-packing of octahedra in the Minkowski lattice – are found to coexist with the binary phase. Apart from an alternative, monoclinic packing of octahedra, no additional crystalline phases were observed.
