DNA-capped gold nanoparticles for the modulation of graphene field-effect-transistors |
| 초록 |
Au nanoparticles of approximately 12nm in diameter capped with single strand DNA are successfully self-assembled on graphene. Hydrophobicity of graphene surface needs to be modified to form uniformly distributed self-assembled DNA capped Au nanoparticles, which is dissolved in water. By optimizing UV-ozone treatment time, agglomeration of DNA capped Au nano particles is avoided. Surface morphologies of DNA capped Au nanoparticle superlattice on graphene are observed by scanning electron microscopy and transmission electron microscopy. Field effect transistors are formed with Graphene-Au nanoparticle 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 nano particles, Graphene-Au nano particle hybrid structure can be applied for opto-electronic device in the future. |
