| 제목 | Preparation of metal nano structure via thin films of diblock copolymers |
| 초록 | Hexagonal and high-density magnetic particle arrays can be applied to memory storage, optical devices, and catalysts. Block copolymers provide a self-assembled template that can also be used for nanolithography with cheaper cost and easier processing. Our research is aimed at fabricating metal nanodots, such as cobalt or nickel, followed by raising carbon nanotubes on them, which can be applied to FED(Field Emission Display). Asymmetric P(S-b-MMA) was spin coated on gold-coated Si wafer and annealed at 150℃ in a vacuum oven for 2 days. After obtaining hexagonally well ordered films, we fabricated polystyrene template with nanoholes after removing the polymethylmethacrylate domains via UV exposure followed by rinsing in acetic acid. Chromium and nickel are successively evaporated onto the template. After removing polystyrene matrix with metal on top, we obtained hexagonally ordered Ni nanodots. We also tried to fabricate cobalt metal patterning by another method, electro-deposition. |
