Abstract :
Point-type carbon nanotube (CNT) field emitters have attracted much interest because they can promise a focused electron beam spot with a high emission current. The point-type CNT field emitters can be used for diverse applications such as x-ray tubes, electron beam sources and microwave sources. Here, we report fabrication and emission performance of various point-type field emitters made by CNTs.
