Synthesis of structurally pure carbon nanotubes using molecular seeds

For the first time, researchers at Empa and the Max Planck Institute for Solid State Research have succeeded in "growing" single-wall carbon nanotubes (CNT) with a single predefined structure - and hence with identical electronic properties. And here is how they pulled it off: the CNTs "assembled themselves", as it were, out of tailor-made organic precursor molecules on a platinum surface, as reported by the researchers in the latest issue of the journal "Nature". In future, CNTs of this kind may be used in ultra-sensitive light detectors and ultra-small transistors.
