ABSTRACT
Enhanced surface diffusion at the growth temperature of single-walled carbon nanotubes (SWNTs) can cause coarsening of metal catalysts. By balancing the nominal thickness and surface diffusion length of metals, metal nanoparticles of desirable size are expected to form spontaneously under the SWNTs growth conditions. Our combinatorial method, using a library of nominally 0.001 to 1 nm thick sputter-deposited cobalt patterns, identified in a single experimental run that cobalt nanoparticles from submonolayers can catalyze the growth of high-quality SWNTs.

    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...
