有序但非周期的准晶体结构的发现要求发展新的衍射方法来确定它们的结构。本文的目的是强调准晶体的非周期性给低能电子衍射（LEED）研究其表面结构带来的挑战。本文描述了迄今为止如何将LEED技术应用于几种准周期表面结构的研究，并总结了这些研究的结果。本文还介绍了Al-Pd-Mn五重表面的点状分析LEED结果。本文还对Al-Pd-Mn的x射线衍射实验和he原子衍射实验进行了比较。
The discovery of ordered but aperiodic quasicrystal structures has required the development of new diffraction methods to determine their structures. The purpose of this review is to highlight the challenges posed by the aperiodicity of quasicrystals to the study of their surface structures by low-energy electron diffraction (LEED). This paper describes how the LEED technique has been thus far adapted to study several quasiperiodic surface structures, and summarizes the results of those studies. It also presents new spot-profile-analysis LEED results from the fivefold surface of Al–Pd–Mn. An x-ray diffraction experiment and a He-atom diffraction experiment, both on Al–Pd–Mn, are also described for comparison.
