Abstract
In summary, the SWCNT and DWCNT point emitters were fabricated by attaching CNT bundles onto the AFM tip using a dielectrophoresis method. We could find that the SWCNT point emitter indicated the better field emission performance compared with the DWCNT point emitter. We expect that the probe type CNT based point emitter can be used in the various applications such as x-ray sources and microwave amplifier tubes which require large emission current density.
