A low density vertically aligned carbon nanotube‐based field‐emission cathode with a ballast resistor and coaxial gate is designed and fabricated. The ballast resistor can overcome the non‐uniformity of the local field‐enhancement factor at the emitter apex. The self‐aligned fabrication process of the coaxial gate can avoid the effects of emitter tip misalignment and height non‐uniformity.
