A high-angle annular dark field scanning transmission electron microscopy study of the intermetallic compound AlCrFe reveals a quasiperiodic structure significantly differing from the ones known so far. In contrast to the common quasi-unit-cells based on Gummelt decagons, the present structure is related to a covering formed by Lück decagons, which can also be described by a Hexagon-Bow-Tie tiling.
对金属间化合物AlCrFe进行的高角度环形暗场扫描透射电子显微镜研究揭示了一种与迄今已知结构显著不同的准周期结构。与基于古梅尔特十边形的常见准晶胞不同，目前的结构与由吕克十边形形成的覆盖结构有关，该结构也可以用六边形-蝴蝶结平铺来描述。
