Quasicrystals represent aperiodically ordered form of solids with symmetries long thought forbidden in nature. Since their discovery, the fundamental key question has been "where are the atoms?" in these novel aperiodic solids, and electron microscopy has indeed provided images of real atomic arrangements in quasicrystals. In this tutorial review, we describe the microscopic view of quasicrystals using state-of-the-art scanning transmission electron microscopy, providing intriguing details that had never been unveiled by the early diffraction-based structural analyses.
准晶代表了一种具有长期以来被认为在自然界中禁止的对称形式的非周期性固体。自从它们被发现以来，一个基本的关键问题是“这些新型非周期性固体中的原子在哪里？”电子显微镜确实提供了准晶体中真实原子排列的图像。在本教程综述中，我们使用最先进的扫描透射电子显微镜描述了准晶体的微观视图，提供了以前基于衍射的结构分析从未揭示过的有趣细节。
