中文摘要：

磷原子链，黑磷(BP ) 的最狭窄的 nanostructures，与深入的发展高度相关基于 BP 一个维(1D )nano 电子学部件。在这研究，我们为磷的准备报导一条自顶向下的线路经由在一台传播电子显微镜(TEM ) 内的电子横梁 sculpturing 的原子链。生长和动力学(即，破裂和边移植) 1D，磷链试验性地第一次被捕获。而且，动态行为和同样形成的磷链的联系 energetics 被密度进一步调查功能的理论(DFT ) 计算。这些 1D BP 结构将用作一个新奇平台并且启发 BP 的万用的性质的进一步的探索，这被希望。

英文摘要：

Phosphorus atomic chains, the narrowest nanostructures of black phosphorus （BP）, are highly relevant to the in-depth development of BP-based one-dimensional （1D） nano-electronics components. In this study, we report a top-down route for the preparation of phosphorus atomic chains via electron beam sculpturing inside a transmission electron microscope （TEM）. The growth and dynamics （i.e., rupture and edge migration） of 1D phosphorus chains are experimentally captured for the first time. Furthermore, the dynamic behavior and associated energetics of the as-formed phosphorus chains are further investigated by density functional theory （DFT） calculations. It is hoped that these 1D BP structures will serve as a novel platform and inspire further exploration of the versatile properties of BP.
