Abstract

The success of nanotechnologies will depend not only on the development of new nanosize materials but also on the way to integrate them in nanodevices. In this context, the fabrication of nano-interconnects with high conductance, low energy dissipation and low resistance at contacts is crucial. An approach is to use carbon nanotubes as template to produce metallic nanowires; improved understanding of interactions at the metal-CNT interface will allow tailoring of properties. After shortly introducing the preparation route of metal nanoparticles on plasma treated carbon nanotubes, the particle-nanotube interaction will be discussed based on XPS, STXM and HRTEM analysis. In the first part, emphasis will be put on electronic properties of Au nanoparticles as well as on the Au-CNT interface formation. The second part will deal with metal particles (Ni or Ti) that form chemical bonds with C. Finally, applications will be presented.
