Carbon nanofibers grown on sodalime glass at 500°C using thermal chemical vapor deposition

Carbon nanofibers are grown homogeneously on a large area of nickel-deposited sodalime glass substrate by thermal chemical vapor deposition of acetylene at 500°C. The diameters of carbon nanofibers are uniformly distributed in the range between 50 and 60 nm. Most of the carbon nanofibers are curved or bent in shape, but some fractions are twisted. They consist of defective graphitic sheets with a herringbone morphology. The maximum emission current density from the carbon nanofibers is 0.075 mA/cm2 at 16 V/μm, which is sufficient for commercializing the carbon-nanofibers-based field emission displays.
