摘　　要：低维材料的结构探索是我们全面认识元素物态的关键.近年来,研究方法的发展使包括一维原子链在内的各种低维结构逐渐被报道.根据一维限域材料的发展现状,本文重点对直径1 nm以下单质材料的结构和物理性质进行了综述,并简要总结了此类研究中常用的实验技术和理论方法.希望通过材料结构特性的解读和研究方法的讨论,说明目前理论计算层面存在的困难及需要面临的挑战,并以此对一维限域材料的研究前景进行展望.Exploring the structure of low-dimensional materials is a key step towards a complete understanding of condensed matter. In recent years, owing to the fast developing of research tools, novel structures of many elements have been reported, revealing the possibility of new properties. Refining the investigation of onedimensional atomic chain structures has thus received a great amount of attention in the field of condensed matter physics, materials science and chemistry. In this paper, we review the recent advances in the study of confined structures under nanometer environments. We mainly discuss the most interesting structures revealed and the experimental and theoretical methods adopted in these researches, and we also briefly discuss the properties related to the new structures. We particularly focus on elemental materials, which show the richness of one-dimensional structures in vacuum and in nanoconfinement. By understanding the binding and stability of various structures and their properties, we expect that one-dimensional materials should attract a broad range of interest in new materials discovery and new applications. Moreover, we reveal the challenges in accurate theoretical simulations of one-dimensional materials in nanoconfinement, and we provide an outlook of how to overcome such challenges in the future.
