| 제목 | The growth mechanism of carbon nano tubes fabricated by Thermoelectrical Pulse Induced Evaporation |
| 초록 | Since carbon nano-tubes (CNT) are discovered, tremendous attention has been paid to this material due to their unique mechanical, electrical and chemical properties. Thereupon, the methods of large-scale production for CNTs are contrived by many scientists and engineers and the growth mechanisms of CNTs, an essential key to produce scale-up, have been naturally attractive. Scientists have been strived to investigate and understand the growth mechanisms of CNTs but it is still controversial. A variety of growth mechanisms are proposed for the formation CNT. We introduce representative growth mechanisms, based on fabricating methods employed broadly. Graphene (hereafter GS), 2-dimemsonal carbon nanostructure, was experimentally discovered and GS have been attracted by both theoretical and experimental groups due to their extraordinary electrical, chemical and mechanical property. There are many limitations on making GS; fabricating large scale GS without any defect and controlling chirality of edge. Thereupon, we apply Thermoelectrical pulse-induced evaporation (TPIE) method based on field and thermal evaporation to the graphene fabrication. On applying this method to synthesis graphene, we found the experimental results of which pioneers have asserted the growth model of CNT. We presented the procedure of growing CNT through TPIE method totally by using Transmission Electron Microscopy (TEM). This study is worth to understand and investigate the carbon based material.
