The selective growth of vertically aligned carbon nanotubes (VACNTs) on large area copper substrates was carried out using a double plasma hot-filament chemical vapour deposition system. Three independent power supplies were used to produce two glow discharges within the vacuum reactor. The generation of two glow discharges and the efficient utilization of the electric fields, by controlling the key process parameters, enabled the production of VACNTs. Morphology, density and structure of carbon nanotubes were characterized using Scanning Electron Microscopy and Raman Spectroscopy.

Nanotube Growth

Large area arrays of vertically-aligned carbon nanotubes (VACNTs) are patterned in a quasi-crystalline Penrose tile arrangement through electron beam lithography definition of Ni catalyst dots and subsequent nanotube growth by plasma-enhanced chemical vapour deposition.
