In this paper, we report a significant improvement of electron field emission property in patterned carbon nanotubes films by using a high temperature (650 °C) hydrogen plasma treatment. This treatment was found to greatly increase the emission current, emission uniformity and stability. The mechanism study showed that these enhanced properties are attributed to the lowering of the potential barrier and the creation of geometrical features through the removal of amorphous carbon, catalyst particles and the saturation of dangling bonds after such a hydrogen plasma treatment.

通过高温氢等离子体处理改善图案化碳纳米管中的电子场发射。

在本文中,我们报告了通过使用高温 (650 °C) 氢等离子体处理显着改善了图案化碳纳米管薄膜的电子场发射性能。发现这种处理大大增加了发射电流、发射均匀性和稳定性。机理研究表明,这些增强的特性归因于势垒的降低和通过去除无定形碳、催化剂颗粒和在这种氢等离子体处理后悬空键的饱和而产生的几何特征。
