美国电报电话公司具尔实验室的科学家们用对新的人工合成金属间化合物的原子结构进行精确的测量和所取得的第一手图像证实了准结晶体(Quasicrystal)的存在。突破的关键是材料处理技术的进步。应用这种技术人们首先得到了高质量的晶体、随后又得到了准结晶体。 R.Becker与他的同事R.Kortan、F.Thiel和H.S.Chen用隧道式扫描电镜观察到了准结晶体个别的表层原子。并用高分辨率的x射线衍射仪与整体材料中的原子进行了比较。Becker说:“这些图像和测量证实了那些成五角形排列的原子集团能结合在一起形成完整的
At AT & T’s scientists at Seoul Telegraph and Telephone Laboratory, the precise measurement of the atomic structure of the new synthetic intermetallic compound and the first hand images obtained confirm the existence of Quasicrystal. The key is to break through the progress of material handling technology. Using this technique, people first got high-quality crystals and then quasi-crystals. R. Becker and his colleagues R. Kortan, F. Thiel and H.S. Chen observed individual surface atoms of the quasi-crystal using a tunnel scanning electron microscope. And compared with the atoms in the bulk material using a high-resolution x-ray diffractometer. Becker said: "These images and measurements confirm that the pentagonal array of atoms can be combined together to form a complete
