本文试图改善石墨阴极（GNF）的场发射特性。采用等离子体辅助化学气相沉积法制备了氮化硼（BN）薄膜。结果表明，由于在平坦的Si衬底上沉积BN纳米晶薄膜，在低阳极电压下发生电子发射。将BN纳米晶薄膜的沉积应用于GNF以改善GNF的场发射特性。除了平均开启电场的降低之外，与生长的GNF相比，发射电流增加了两个数量级。
An improvement in field emission characteristics of a graphite nanofiber (GNF) has been attempted. Boron nitride (BN) films are synthesized by plasma-assisted chemical vapor deposition. It is demonstrated that electron emission occurs at a low anode voltage due to depositing the BN nanocrystalline film on flat Si substrates. Deposition of the BN nanocrystalline film is applied to the GNF to improve the field emission characteristics of the GNF. In addition to a reduction in the average turn-on electric field, the emission current increases by two orders of magnitude in comparison with that of an as-grown GNF.
