In this work, the mechanical properties of C(60) molecules adsorbed on Cu(111) are measured by tuning-fork-based noncontact atomic force microscopy (nc-AFM) and spectroscopy at cryogenic conditions. Site-specific tip-sample force variations are detected above the buckyball structure. Moreover, high-resolution images obtained by nc-AFM show the chemical structure of this molecule and describes unambiguously its orientations on the surface.
在这项工作中，通过基于音叉的非接触原子力显微镜（nc-AFM）和低温条件下的光谱测量，测量了吸附在 Cu(111)上的 C(60)分子的力学性能。在巴基球结构上方检测到了针尖-样品力的特定位置变化。此外，nc-AFM 获得的高分辨率图像显示了该分子的化学结构，并明确描述了其在表面上的取向。
