다국어 초록 (Multilingual Abstract)

The ultimate goal of our study is to form noble metal nanoparticles on the surface of multi-walled carbon nanotubes (MWCNTs) via physical processes for electronic applications. Nobel metal nanoparticles have attracted a great deal of recent interest due to their unique optical properties as a result of localized surface plasmon resonances (LSPR). In this study, our processes create defects on MWCNTs, in which various transition metal hydrates are physically adsorbed onto the surface of carbon nanotubes. Then, transition metal oxide nanoparticles are produced on the MWCNTs under a condition of relative low temperature and atmospheric environment. Simultaneously, the oxide nanoparticles move along the surface of MWCNTs and subsequently generate defect sites by acid treatment. Here, we present the evidences of defect sites produced by our processes and effects of different types of transition metals.
