Abstract :
In this report, we present an alternative approach in which a femto-second pulsed laser beam is employed to cut and trim multi-wall carbon nanotubes (MWCNTs) as predetermined. By using this technique, we are successful to fabricate CNT-tip based cathodes. A very high current and stable field emission are recorded from those emitters.
