Abstract :
This study presents a novel selective growth method to pattern the high purity and single-walled carbon nanotubes (SWNTs) network by alcohol catalytic chemical vapor deposition (ACCVD). A hydrophilic surface with a contact angle of 44.22deg or even lower can disperse the Co-Mo catalysts easily and uniformly. Therefore, the SWNTs networks can be only formed and grown on the surface of SiO2 layer after a highly hydrophilic surface treatment. This novel method can be applied in the process of SWNTs electronics devices such as nanosensors or transistors. Finally, a SWNTs networks field effect transistor was also fabricated and demonstrated.
