Abstract
Individual single-walled carbon nanotubes (SWNTs) were synthesized directly on a Si/SiO 2 substrate by chemical vapor deposition using methane as the feedstock and nickel sulfate as the catalyst precursor. This new surface growth approach yields SWNTs of diameter 0.7-3 nm and lengths of up to tens of micrometers. The SWNTs were characterized with scanning electron microscopy, atomic force microscopy, Raman spectroscopy, and electron transport measurements. Both metallic and semiconducting SWNTs were identified.
