Graphene-Au nanopartcle hybrid structure by DNA assisted self-assembly |
| 초록 |
Au nanoparticles (NPs) of approximately 12nm in diameter capped with single-strand DNA are successfully self-assembled on graphene. Hydrophobicity of graphene surface needs to be modulated to form uniformly self-assembled DNA capped Au NPs, which is dissolved in water. By optimizing UV-ozone treatment time, agglomeration of DNA capped Au NP superlattice on graphene are observed by scanning electron micriscopy and transmission electron microscopy. Field effect transistors are formed with graphene-Au NP hybrid structure to characterize its electrical properties. N-doping effect on graphene is observed due to negatively charged DNA. By utilizing surface plasmon enhancement from Au NPs, graphene-Au NP hybrid structure can be applied for optoelectronic device in the future. |
