摘要

Carbon nanofibers (CNFs) with various structures were synthesized using electroplated nickel catalysts on diverse metal buffer layers via hot-filament chemical-vapor-deposition method. High-density thick CNFs were grown on copper and gold buffer layers whereas low-density thin CNFs were grown on chromium and titanium buffer layers. All CNFs revealed solid structure without hollow cores, and graphitic platelets of CNFs consisted of a mixed structure of stacked and herringbone arrangement. CNF films grown on gold buffer layers showed high-emission-current density and temporal stability: 170 mA/cm~2 at 7.3 V/μm, and 10.3% fluctuation over 10 h at the current density of 6 mA/cm~2, respectively.
