Abstract

Recently, carbon nanotubes (CNTs), possessing excellent properties as field emitters, are attracting considerable attention as electron emitters of a cold cathode. In this review article, field emission phenomena of carbon nanotubes with various morphologies and surfaces (clean surface or adsorbed molecules on it) revealed by field emission microscopy are first described. Then, the main subject of this article, application of CNTs as electron sources in display devices is reviewed. Other electric devices utilizing CNT-field emitters are also presented.

摘要

最近，作为具有优异场发射特性的场发射体，碳纳米管（CNTs）作为冷阴极的电子发射体正吸引着相当多的关注。在这篇综述文章中，首先描述了通过场发射显微镜揭示的具有各种形态和表面（清洁表面或其上吸附分子）的碳纳米管的场发射现象。然后，综述了本文的主要主题，即碳纳米管在显示器件中作为电子源的应用。还介绍了其他利用碳纳米管场发射体的电子器件。
