Abstract

Nanowires and nanotubes have attracted much interest as potential building blocks for nanotechnology. This interest can be traced to the novel structural and electronic properties of these nanomaterials. Here we describe a study that measures the electronic properties of bare LiMo3Se3-nanowires, together with wires that have been stabilized by alkylammonium- and pyridinium-ligands. The bare LiMo3Se3-nanowires consist of individual wire bundles whereas the stabilized wires form networks with an inter-wire spacing determined by the ligand. The bare wires are shown to be metallic but susceptible to electrical degradation (oxidation) in air. However, conductivity measurements at different temperature and oxidation times show that conduction in the wire networks occurs via a percolation mechanism and is activated. Moreover, the corrosion rate of the Mo3Se3-nanowires is dramatically reduced when the wires are stabilized, demonstrating that the ligands form a protective semi-insulating coating.
