Crystallography of quasiperiodic crystals
WebThe development of the concept of quasicrystals has challenged many widely held assumptions of crystallography and solid state physics. It had been generally assumed that pentagonal symmetry is impossible in solids, that Bragg diffraction peaks imply periodic translational order, that all pure solids are either crystalline or glassy, and that the … WebThe IUCr is a scientific union serving the interests of crystallographers and other scientists employing crystallographic methods.

WebAn-Pang Tsai, Can Cui, in Handbook of Crystal Growth (Second Edition), 2015. Abstract. Quasicrystals (QCs), which reveal diffraction patterns with symmetries forbidden in crystallography and quasiperiodicity, have been found to be stable phases in several alloy systems. Because of this stability, one can grow single-grained QCs on a large scale by … WebCrystallography treated order and periodicity synonymously, both serving equally to define the notion of a crystal.
