Carbon nanocoils (CNCs) were synthesized via thermal chemical vapour deposition (CVD) with C2H2 and NH3 gases at 600 °C. A Ni catalyst was placed upon the copper micro-tip structures that were fabricated on a silicon substrate. Our CNCs had a long rope shape with a length not exceeding 100 µm and a nanoscale diameter. The copper micro-tips were formed through high current pulse electroplating, which played a significant role in characterizing our CNCs. The CNCs grown on the copper micro-tips showed outstanding field emission performance and long-term stability. Their turn-on field, defined as that at a current density of 10 µA cm−2, was 1.30 V µm−1 and the maximum current density reached 11.17 mA cm−2 at an electric field of 2.39 V µm−1.
