Abstract
Nanosized platinum clusters were grown on a TiO2(110) surface and annealed in ultrahigh vacuum at high temperatures. This leads to the so-called stron g metal-support interaction (SMSI) state, characterized by a complete encap sulation of the clusters with a reduced titanium oxide layer. We present at omically resolved scanning tunneling microscopy measurements of the cluster surfaces and an atomic model of the SMSI state. The ability to resolve the cluster surface geometry with atomistic detail may help to identify the ac tive sites responsible for the SMSI.
