Growth and field emission properties of vertically aligned carbon nanofibers
Vertically aligned carbon nanofibers sVACNFsd were synthesized on Ni-coated Si substrates using a dc plasma-enhanced chemical-vapor deposition system. The size of the Ni islands used as catalyst to grow the VACNFs was formed by both thermal annealing and laser processing on thin metal layers. It was observed that the diameter of the carbon nanofibers is strongly dependent on the initial Ni isla...
متن کاملReversible electrowetting of vertically aligned superhydrophobic carbon nanofibers.
Reversible electrostatically induced wetting (electrowetting) of vertically aligned superhydrophobic carbon nanofibers has been investigated. Carbon nanofibers on a 5 x 5 microm pitch were grown on Si substrates, electrically insulated with a conformal dielectric, and hydrophobized with fluoropolymer. This nanostructured scaffold exhibited superhydrophobic behavior for saline (theta approximate...
متن کاملOptimized Conditions for Catalytic Chemical Vapor Deposition of Vertically Aligned Carbon Nanotubes
Here, we have synthesized vertically aligned carbon nanotubes (VA-CNTs), using chemical vapor deposition (CVD) method. Cobalt and ethanol are used as the catalyst and the carbon source, respectively. The effects of ethanol flow rate, thickness of Co catalyst film, and growth time on the properties of the carbon nanotube growth are investigated. The results show that the flow rate of ethanol and...

متن کاملWafer-scale fabrication of a vertically-aligned NEMS switch based on carbon nanofibers
Fabrication of nanoscaled transistors based on carbon nanotubes and inorganic nanowires is typically demonstrated with a “pick-and-place” or similar method which allows for fabrication of small numbers of transistors at a time. While these, and other, devices have been used to demonstrate potential applications of carbon nanotubes, these methods are not applicable to wafer scale production with...
