The formation of recumbent bamboo-like carbon nanotube patterns on a patterned gold substrate by chemical vapor deposition

The pyrolysis of iron(II) phthalocyanine on an Au substrate under an atmosphere of ethanol/argon was found to produce recumbent bamboo-like multi-walled carbon nanotubes. By changing the pattern of the Au bars in the substrate, the configuration of the nanotube could be changed. A possible mechanism for the formation of these patterns is suggested.
