Strobel, Christoph H. Bleuel, Hannes Marsteller, Alexander Growth modes of thin films of ligand-free metal clusters Tang, Xin Dollinger, Andreas Ganteför, Gerd Kim, Young Dok Marsteller, Alexander Tang, Xin Bleuel, Hannes eng 2015-07-28T05:46:03Z Ganteför, Gerd Size-selected Mo <sub>n</sub> <sup>−</sup>, W<sub>n</sub> <sup>−</sup>, and Fe<sub>n</sub> <sup>− </sup>cluster anions are deposited on a weakly interacting substrate (highly oriented pyrolytic graphite) and studied ex-situ using atomic force microscopy. Depending on size, three growth modes can be distinguished. Very small clusters consisting of less than 10–30 atoms behave similar to atoms and coalesce into 3-dimensional bulk-like islands. Medium sized clusters consisting of hundreds of atoms do not coalesce and follow a Stanski-Krastanov growth pattern. At low coverage, an almost perfect monolayer is formed. This is a new finding different from all previous studies on deposited metal clusters. For clusters with several thousands of atoms, the growth pattern again changes. At low coverage, the substrate is dotted with individual clusters, while at high coverage, the surface becomes extremely rough. 2015 Strobel, Christoph H. 2015-07-28T05:46:03Z Bowen, Kit H.
