本文获得了定向石墨纳米纤维的场发射数据。排列的纳米纤维直径为50 ~ 100 nm，长度为6 ~ 10 μm，密度为109 ~ 1010/cm2。采用等离子体辅助热丝化学气相沉积的方法，利用氮气和乙炔的混合物在多晶镍基体上生长纤维。发射起始电流约为1.8 V/μm，发射面积为1 mm2。采用Fowler-Nordheim模型对所得数据进行分析。平板显示器所需的场发射电流在2.5 V/μm即可轻松实现。
Field emission data from aligned graphitic nanofibers have been obtained. The aligned nanofibers are 50–100 nm in diameter and 6–10 μm in length, with a density of 109–1010/cm2. The fibers were grown on polycrystalline nickel substrate by plasma-assisted hot filament chemical vapor deposition using a gas mixture of nitrogen and acetylene. The onset of emission current in microampere level was detected at about 1.8 V/μm with an emission area of 1 mm2. The Fowler–Nordheim model was used to analyze the data obtained. The field emission current required for flat panel display can be easily achieved at 2.5 V/μm.
