Size-dependent melting of self-assembled indium nanostructures - art. no. 095505

We have measured the melting temperature of nanoscale indium islands on a W Se2 substrate using perturbed angular correlations combined with scanning t unneling microscopy. The indium islands are self-assembled nanostructures w hose diameter can vary between about 5 and 100 nm, depending on deposition conditions. The melting point decreases due to surface energies as the isla nds get smaller. This decrease depends on the faceting of the crystalline n anostructures and interactions between the islands and the substrate.
