摘要：
Single-walled carbon nanotubes (SWNTs) have been synthesized by a laser-irradiated chemical vapor deposition (LICVD), where a laser with 514.5 nm was used as a source of heat. The irradiation laser power dependence was investigated for growth of suspended SWNTs. On the basis of the results, the suspended SWNTs were formed between the patterned catalysts at irradiation power of 5 mW by LICVD method. The 514.5-nm Raman scattering spectroscopy measurement revealed that the radial breading mode was clearly observed. As a result of the resonant effect, SWNTs, which are resonant to irradiation laser with 514.5 nm, might be easily bridged between the patterned catalysts.
