摘      要：In this work,different effects of substrates on the morphologies of single-walled carbon nanotubes(SWNTs)are *** were produced by floating catalytic chemical vapor deposition using CH4as carbon source gas and Ar as carrier *** the SWNTs were deposited on lithography-patterned different *** as-grown SWNTs at the boundaries between SiO2and metal were characterized by scanning electron microscopy,atomic force spectroscopy and Raman *** is found that SWNTs deposited on low-conductivity substrates trend to have curved morphologies and some of them form rings,while SWNTs deposited on metal substrates remain straight and *** mechanism of these effects was also discussed,which is closely related to the thermal conductivities and the principle of energy dissipation.
