Abstract: In this study, we demonstrated a line-type carbon nanotube (CNT) field emitter, which emits electrons from its line-edge, as for a sheet electron beam source. We also proposed a novel cathode structures for obtaining sheet electron beams with a high-quality and a high-aspect-ratio. The line-type CNT field emitters show an emission current of up to 45 mA, which corresponds to an emission current density of 150 A/cm2 and well-confined sheet electron beams with an improved emission stability. We expect that the excellent performance of the sheet electron beam source can be applied to various next-generation applications such as high-resolution micro-CT and high-power microwave amplifiers.
