Popis: | A two-step masking technique has been developed to prepare large-scale triangular lattice arrays of uniform sub-micron islands on substrates at room temperature and at low cost by utilizing self-assembly of polystyrene microspheres. As an example, fabrication of large arrays of nickel islands with long-range periodicity and morphological uniformity is demonstrated, which is also ready to apply to fabricate periodic sub-micron islands of other materials on flat substrates in general. The islands so prepared resemble the shape of a hexagonal disc with its size determined by the size of the polystyrene spheres and its thickness variable in a wide range. These islands of various materials on different kinds of substrates can be used in a variety of applications such as catalysts to grow aligned carbon nanotubes and nanowires for 2D photonic crystals, nanoelectrode arrays for molecular devices, nanostructure building blocks for nanofabrications, etc. |
