An Overview of Quasicrystals, Their Types, Preparation Methods, Properties
(Islamic Azad University , Karaj Branch , Karaj , Iran, 2021-06-01)Quasicrystals, unlike crystals that contain regular and repetitive patterns, are composed of regular patterns that are not repetitive. Moreover, the symmetry of quasicrystals in crystals is impossible. For example, ordinary ...
