摘要

RE - Au - Si (RE=Ho, Tb)体系是具有团簇中心修饰的1/1 Tsai型准晶近似体，可以是无序四面体，也可以是稀土原子。用扫描透射电子显微镜观察了三种不同样品的局部原子结构，并用高角度环形暗场模拟扫描透射电子显微镜图像对其进行了解释。研究发现，这两种方法的结合可以通过对线形的定量分析来识别簇中心化学装饰的差异。

STEM Structural Investigation of RE-Au-Si 1/1 Approximants

RE-Au-Si (RE=Ho, Tb) systems are 1/1 Tsai-type quasicrystalline approximants with a cluster center decoration that can vary from a disordered tetrahedron to a rare-earth atom. The local atomic structure of three different samples was observed by scanning transmission electron microscopy and interpreted in the light of high-angle annular dark field simulated scanning transmission electron microscopy images. It is found that the combination of these two methods allows to identify differences in the chemical decoration of the cluster centers through quantitative analysis of line profiles.

期刊介绍： The fledgling State of Israel began to publish its scientific activity in 1951 under the general heading of Bulletin of the Research Council of Israel, which quickly split into sections to accommodate various fields in the growing academic community. In 1963, the Bulletin ceased publication and independent journals were born, with Section A becoming the new Israel Journal of Chemistry. The Israel Journal of Chemistry is the official journal of the Israel Chemical Society. Effective from Volume 50 (2010) it is published by Wiley-VCH. The Israel Journal of Chemistry is an international and peer-reviewed publication forum for Special Issues on timely research topics in all fields of chemistry: from biochemistry through organic and inorganic chemistry to polymer, physical and theoretical chemistry, including all interdisciplinary topics. Each topical issue is edited by one or several Guest Editors and primarily contains invited Review articles. Communications and Full Papers may be published occasionally, if they fit with the quality standards of the journal. The publication language is English and the journal is published twelve times a year.
