不同于传统的晶体,准晶由非单一的结构单元以一种非重复的方式铺满空间而构成.准晶的形成依赖于短程序和长程序之间微妙的协同,因此准晶常常只在很窄的参数窗口内能得到.近年来,人们利用纳米以至微米级的结构单元,通过溶液中自组装或者在模板上生长,成功地获得了多种大尺寸结构单元的准晶结构.近年的研究还发现,在自然界的矿物中和中世纪伊斯兰建筑装饰上都能找到准晶结构.对准晶结构的多角度、多学科探索,有助于实现准晶的人工设计和生长.
Unlike traditional crystals, quasicrystals consist of a non-unitary unit of structure covering a space in a non-repeating manner. The formation of quasicrysts relies on the subtle coordination between short and long programs, Very narrow parameter window can be obtained.In recent years, the use of nanoscale and micron-scale structural units, by self-assembly in solution or in the template growth, successfully obtained a variety of large-size structure quasicrystal structure unit. The study also found that quasicrystal structures can be found both in the minerals of nature and in medieval Islamic architectural decoration, and multi-angle and multidisciplinary exploration of the quasicrystal structure can help to realize quasicrystal design and growth.
