Charge and energy quantization phenomena in systems of ligand-stabilized metal clusters analyzed by scanning probe microscopy

配体稳定的金属团簇具有基础和应用的重要性，可以与裸团簇相比，在环境条件下进行研究。本项目的主要目标是利用扫描隧道显微镜和光谱学研究Au55[P(C6H5)3]12Cl6化合物的电子性质。在最近的一些工作中，我们第一次测量了团簇的离散能级，并且长期以来我们研究了由于单电子隧穿引起的电荷量子化。在此基础上，本项目建议对星团的能级分裂进行更详细的分析。此外，相邻团簇之间以及团簇与底物之间的相互作用也是令人感兴趣的。

Ligand-stabilized metal clusters are of fundamental as well as of applied importance and can in contrast to naked clusters be investigated under ambient conditions. The main goal of the present project is to investigate the electronic properties of the well-known Au55[P(C6H5)3]12Cl6 compound by scanning tunneling microscopy and spectroscopy. In some recent work we could measure for the first time discrete energy levels of the cluster, and since a long time we study charge quantization due to single electron tunneling. Based on that work a more detailed analysis of the energy level splitting of the clusters is suggested within the present project. Additionally the interaction between adjacent clusters as well as between clusters and substrates is of interest.
