Direct imaging of Pd561(phen)38±2On and Au55(PPh3)12Cl6 clusters using scanning tunneling microscopy


  • This work was part of the research program of the Stichting voor Fundamenteel Onderzoek der Materie (FOM) and was made possible by financial support from the Nederlandse organisatie voor Zuiver Wetenschappelijk Onderzoek (ZWO) and from Philips Research Laboratories. We would like to thank J. van Ruitenbeek of the Kamerlingh Onnes Laboratory in Leiden for helpful discussions.


The first images of isolated full-shell ligand-stabilized clusters have been obtained using STM (see figure). The clusters are ideal model systems for studying the relationship between cluster size and electronic properties as well as having applications in catalysts and filters.
