Antimony nanowires self-assembled from Sb nanoparticles

Article Abstract:

A simple method of synthesizing segregated thin antimony nanowires is introduced, based on the principle that nanoparticles could spontaneously self-assemble into crystalline nanowires in the absence of any rigid templates at room temperature. The effect of nanowire diameter is investigated on plasmon excitations in Sb nanowires, by collecting electron energy loss spectra from individual Sb nanowires with different diameters.

Modulation of the electronic structure of semiconducting nanotubes resulting from different metal contacts

Article Abstract:

The role of the metal electrode influencing the structure and electronic properties of semiconducting carbon nanotubes near the interface at low bias is examined. The calculations at the density functional level of theory, including full geometry optimizations, indicates that bonds are formed between the metal atoms of the electrode and the carbon atoms of the nanotubes.

Geometrical and electronic structures of gold, silver, and gold-silver binary clusters: origins of ductility of gold and gold-silver alloy formation

Article Abstract:

The structures of neutral and anionic gold-silver binary clusters and pure gold and silver clusters are investigated. It is shown that the calculated electronic properties and dissociation energy of both pure and binary clusters are in agreement with the available experimental data.
