1. Introduction Recently, carbon nanotubes have attracted a lot of interest because of their outstanding electrical properties and their potential application as a possible material for fabrication of cold cathodes [1-3]. It was found that the field enhancement from carbon nano-tubes exhibited large local field enhancement and considerable field emission currents at relatively low applied voltage. Carbon nanotube-based field emission displays have been fabricated using well-aligned nano-tubes … 相似文献
