Carbon nanotubes have been shown to behave as very effective conductors and semiconductors, but their electronic uses are limited by how well metallic and semiconducting nanotubes can be sorted. Recent investigations have shown an effective method of separating laser ablation–produced carbon nanotubes by electronic type. However, laser ablation nanotubes are no longer produced. This investigation of arc discharge carbon nanotubes has yielded some candidates for substitutes. Carbolex’s nanotubes yield a high-purity semiconductor sorting. Carbon Solutions Inc.’s nanotubes show limited metallic sorting. These results can be used to further optimize the sorting process and to ultimately find a replacement for laser ablation–produced nanotubes.
