Synthesis of well-aligned carbon nanotube network on a gold-patterned quartz substrate

A network of carbon nanotubes with high alignment was synthesized on a gold-patterned quartz substrate due to the different growth rates of nanotubes on Au and quartz. Controlled fabrication of nanotube networks on a large area could be realized simply by treating the Au film into a corresponding pattern. This provides a practical way to obtain aligned nanotube networks on combined substrates for further building large-scale functional devices.
