The aim of the project is the investigation of carbon nano-peapods by scanning force microscopy and spectroscopy in ultrahigh vacuum and at low temperatures. First, the correlation between structural, local electronic and mechanical properties of carbon nano-peapods will be studied by dynamic non-contact atomic force microscopy. Second, the formation mechanism of carbon nano-peapods by means of molecular manipulation and direct observation by NC-AFM will be investigated. The final goal of the project is the manufacturing of a "perfect" nano-bearing. All these experiments require UHV-based NC-Afm methods of highest technical performance including threedimensional force field spectroscopy with true atomic resolution on curved surfaces which only recently became available as demonstrated for pure single-walled carbon nanotubes.

该项目的目的是通过扫描力显微镜和光谱学在超高真空和低温下研究碳纳米豆荚。首先，将通过动态非接触原子力显微镜研究碳纳米豆荚的结构、局部电子和机械性能之间的相关性。其次，将通过分子操纵和NC-AFM直接观察来研究碳纳米豆荚的形成机制。该项目的最终目标是制造“完美”的纳米轴承。所有这些实验都需要具有最高技术性能的基于 UHV 的 NC-Afm 方法，包括在曲面上具有真正原子分辨率的三维力场光谱法，这种方法最近才变得可用，如纯单壁碳纳米管所证明的那样。
