摘要：
Surface functionalization of suspended single-walled carbon nanotubes(SWNTs) using metal(Au) nanoparticles(NPs) is reported.SWNTs are grown on three-dimensionally patterned substrates by thermal chemical vapor deposition and successfully functionalized with Au NPs.Ethylendiamine is mainly used to functionalize SWNTs surface with amino groups before introducing Au NPs.From Raman scattering spectroscopy of the Au-functionalized suspended SWNTs,enhanced Raman scattering properties are obtained.The results suggest that the attached Au NPs may contribute to the enhancement of resonant phenomena.By measuring the electric properties after each functionalization process,it is found that Au NPs act as electron acceptor to the amine functionalized SWNTs.
