Synthesized nanotubes had mean diameters of 20 ～ 50 nm and several ㎛ length. The kind of catalysts affected microstructures of SiC nanotubes by different diffusion routes. These differences are attributed to catalysts' physical properties and relative activities to the graphite substrate. Fe acted as a good catalyst of SLS growth mechanism. But in case of Ni, SiC nanotubes grew slowly. Optical property was measured by photoluminescence measurement. Relatively broad peak was obtained and mean peak positioned at about 430 nm. This result was the same as other nanocrystalline SiC materials, but was different from the results of bulk SiC probably due to quantum confinement effect and defect in the grown SiC nanotube. 한국재료학회 SLS(Solid-Liquid-Solid) 성장기구에 의한 탄화규소 나노튜브의 성장 Growth of SiC Nanotube by SLS (Solid-Liquid-Solid) Growth Mechanism Article 2 한국재료학회지, v.14, no.2, pp.83 - 89 한국재료학회지 14 2 83 89 kci ART000932044 SiC nanotube SiC nanotube SLS (solid-Liquid-Solid) growth mechanism SiC nanotube SiC nanotube SLS (solid-Liquid-Solid) growth mechanism
