Crystallography of quasiperiodic crystals
Did you know?
A quasiperiodic crystal, or quasicrystal, is a structure that is ordered but not periodic. A quasicrystalline pattern can continuously fill all available space, but it lacks translational symmetry. While crystals, according to the classical crystallographic restriction theorem, can possess only two-, three-, four-, and six-fold rotational symmetries, the Bragg diffraction pattern of quasicrystals shows sharp peaks w… WebInternational Tables for Crystallography (2006).

The face configuration is used for the description of face-transitive poly-hedra.
WebQuasiperiodic structures (QSs), incommensurately modulated structures (IMSs) and composite structures (CSs) are the main types of aperiodic crystal structures (Cummins … WebThe structure and symmetry of quasiperiodic crystals can be described by embedding them into a higher-dimensional space as lattice periodic structures. Their intersection with the physical space gives the real structure, shifting the physical space parallel to the original one gives another possible realization of the crystal with the same energy.
