Abstract :
Carbon nanotubes were formed on HOPG when the graphite faces were exposed to a stainless steel C60 evaporator heated to 450°C. No nanotubes were found on gold under the same conditions or when a quartz oven was used as the C60 evaporator. Interesting conical nanostructures were found in the insoluble residue from the stainless steel oven. We interpret the nanotube formation to be due to the presence of small carbon fragments produced by the catalytic decomposition of C60 in the oven.
