Preformed Co clusters with an average diameter of 2.5 nm are produced in the gas phase and are deposited under controlled ultra-high vacuum conditions onto a thin insulating NaCl film on Au(111). Relying on a combined experimental and theoretical investigation, we demonstrate visualization of the three-dimensional atomic structure of the Co clusters by high-resolution scanning tunneling microscopy (STM) using a Cl functionalized STM tip that can be obtained on the NaCl surface. More generally, use of a functionalized STM tip may allow for systematic atomic structure determination with STM of nanoparticles that are deposited on metal surfaces.
平均直径为2.5纳米的预形成钴团簇在气相中生成，并在超高真空控制条件下沉积到金（111）表面的薄绝缘氯化钠薄膜上。通过结合实验和理论研究，我们利用可在氯化钠表面获得的氯功能化扫描隧道显微镜（STM）尖端，通过高分辨率扫描隧道显微镜（STM）展示了钴团簇的三维原子结构。更一般地说，使用功能化STM尖端可能允许通过STM对沉积在金属表面的纳米颗粒进行系统的原子结构测定。
