We describe a simple technique to grow small (approximately 1-4 nm) diam carbon nanotubes both in and out of the plane of a silicon substrate using the decomposition of ethylene and a nickel-iron thin film catalyst. This procedure can be used to produce nanotubes for ultrasharp atomic force microscope probes as well as for nanotube-based electronic devices. The technique is compatible with the patterned growth of nanotubes and with standard device microfabrication processes.

    In the formation of single-wall carbon nanotubes (SWNTs) by laser ablation and arc discharge, metal catalysts are necessary. We found that NiCo was the most effective in catalyzing SWNT formation and that other metals followed the order NiCo>Ni∼NiFe>>Co∼Fe. We confirmed that all these...
