横向操纵单个原子和分子以在表面上创建人工结构的能力(1) 正在推动我们更接近二维纳米工程的终极极限(2,3)。然而，涉及这种水平操作的实验仅在低温下进行。迄今为止，扫描隧道显微镜已被证明是一种独特的工具，具有横向推动、拉动或滑动(4)单个原子和分子并将它们随意排列在表面上的所有必要功能。在这里，我们首次证明，即使在室温下，也可以使用近接触原子力显微镜 (5-7) 对单个原子进行良好控制的横向操纵。我们报告了“原子镶嵌”的创建，即由表面平面上的一些嵌入原子形成的人造原子图案。在室温下，这种原子结构在相对较长的时间内在表面上保持稳定。
The ability to manipulate single atoms and molecules laterally for creating artificial structures on surfaces(1) is driving us closer to the ultimate limit of two-dimensional nanoengineering(2,3). However, experiments involving this level of manipulation have been performed only at cryogenic temperatures. Scanning tunnelling microscopy has proved, so far, to be a unique tool with all the necessary capabilities for laterally pushing, pulling or sliding(4) single atoms and molecules, and arranging them on a surface at will. Here we demonstrate, for the first time, that it is possible to perform well-controlled lateral manipulations of single atoms using near-contact atomic force microscopy(5-7) even at room temperature. We report the creation of 'atom inlays', that is, artificial atomic patterns formed from a few embedded atoms in the plane of a surface. At room temperature, such atomic structures remain stable on the surface for relatively long periods of time.
