We have reported the catalyst-assisted hot-filament chemical vapor deposition (HFCVD) of various carbon nanostructures, such as carbon nanotube (CNT), nanoparticle (CNP), and nanofiber (CNF), and their application examples. In the case of CNT, vertically aligned high-density growth has been investigated in detail using in-situ optical reflectivity measurement. For CNF showing large field-emission...
Cold cathodes which can emit high currents were fabricated using carbon nanofiber (CNF) films synthesized via hot-filament chemical vapor deposition (HFCVD) method. The synthesis of CNF films with good electron-emitting characteristics relied on the judicial choice of metal catalysts. As it turned out electroplated nickel catalysts on gold buffer layers was suitable for the synthesis of CNFs with...
