Abstract
Carbon nanofibers (CNFs) were grown on copper micro-tips formed by electroplating. The nickel layer electroplated over the copper micro-tips was used as a catalyst. The CNFs were synthesized by using plasma-enhanced chemical vapor deposition (PECVD) of C2H2 and NH3 at 480 °C. The copper micro-tips were formed by high current pulse electroplating, which played a significant role in characterizing our CNFs. The CNFs grown on the copper micro-tips showed outstanding field emission performance and stability, whose turn-on field, defined as one at the current density of 10 μA/cm2, was 1.30 V/μm and the maximum current density reached 5.39 mA/cm2 at an electric field of 4.9 V/μm.
