研究了碳化钛（TiC）涂层碳纳米管（CNT）阵列的场发射特性。镀TiC薄膜后，场发射的导通电压大大降低，发射位点增加。结果表明，结合TiC的低功函数和CNTs的高长宽比，可以有效地制备出高质量的场致发射体。
Field emission properties of titanium carbide (TiC) coated carbon nanotube (CNT) arrays have been investigated. The turn-on voltage of field emission is largely decreased and the emission sites are increased after the coating of TiC thin films. It is evidenced that the combination of the low work function of TiC and the high aspect ratio of CNTs is effective for the fabrication of high quality field emitters.
