Multilayered heterogeneous one-dimensional (1-D) nanostructures are important building blocks for nanodevice applications. A practical nanofabrication technique to produce heterogeneous nanostructures with arbitrary materials must have the ability to control the dimensions and uniformity, to control the alignment, and to control the interfacial properties of the heterogeneous nanostructures. In this...
In this paper, a non-lithographic technique that produces organized nanoscale nickel catalyst for carbon nanofiber growth on a silicon substrate is described. This technique involves three consecutive steps: first, the substrate is laser-irradiated to produce a periodic nano rippled structure; second, a thin film of nickel is deposited using glancing angle ion beam sputter-deposition, followed by...
