Abstract

The synthesis of vertically aligned nanocluster wires (NCW) on indium-tin-oxide-coated glass substrates by the thermal decomposition of Fe(CO)5 with a resistive heater under a magnetic field was discussed. It was shown that the aligned NCW was controlled by varying the flow rate of carrier gas. It was found that the low-density NCWs showed better field emission characteristics, with a low turn-on field of about 4 V/μm and a current density as high as 3 mA/cm2 at 7.6 V/μm. The field enhancement factor (γ) was determined to be ∼1200 for high-density NCWs and ∼1600 for low-density NCW.
