Atomic-size reaction field for frontier material creation using atom manipulation experiments

在本研究中，我们利用扫描隧道显微镜(STM)和非接触原子力显微镜(NC-AFM)来实现原子大小的反应场，并制造由多个原子组成的纳米团簇。我们使用了Si(111)-(7×7)表面的半单元电池作为一个小尺寸的反应场所。我们操纵蒸发的单个原子，如铅、金和银，形成纳米团簇。我们在反应场所成功地制备了由单一元素和两种元素组成的合金团簇。我们还成功地揭示了聚集在一起的银或金原子的最大数量。

In this study, using Scanning Tunneling Microscopy (STM) and Non-contact Atomic Force Microscopy (NC-AFM) , we aimed at realizing atomic size reaction field and manufacturing nano-cluster composed of several atoms. We used half-unit-cells of the Si(111)-(7x7) surface as a small-size reaction place. We manipulated evaporated single atoms such as Pb, Au, and Ag to make nano-clusters. We successfully made alloy cluster composed of one and two elements on the reaction place. We also succeeded in revealing maximum number of the Ag or Au atoms that clusters.
