摘要

近年来,碳纳米管由于具有低阈值的发射电场和高的发射电流密度而成为很有前途的电子发射材料。这些特点使它们对许多技术应用具有吸引力,例如用于各种真空电子设备的冷阴极电子源。本文模拟了随机取向碳纳米管在外加电场作用下的场发射行为。

Modeling of the behavior of random carbon nanotubes during field emission
Carbon nanotubes (CNTs) have emerged as promising electron emitters in recent years because of their low threshold electric field for emission and a high emission current density. These features make them attractive for many technological applications such as cold cathode electron sources for a variety of vacuum electronic devices. In this paper, we model the behavior of randomly oriented CNTs during field emission under the influence of external electric field.
