摘要

碳纳米管具有优异的场发射性能;它们可以用作场发射(FE)冷阴极。本文采用热化学气相沉积法在传统的热阴极表面直接合成CNTs;通过改变催化剂的溅射时间，发现溅射时间对发射性能有很大的影响，并进行了讨论。

Preparation of high field emission current carbon nanotubes by chemical-vapor deposition

Carbon nanotubes (CNTs) have excellent performance in field emission; they can be used as field emission (FE) cold cathode. In this paper, we used thermal chemical vapor deposition to synthesize CNTs directly on the surface of traditional thermal-cathode; we changed the sputtering time of catalyst and found that it had a major impact on the emission properties, some discussion were also give.
