1. A field emission device comprising:

  • a substrate;

    a conductive row being disposed on the substrate;

    a non-conducting amorphous carbon layer including a layer of hydrogen-free amorphous carbon being non-conductive and being disposed on the substrate/conductive row;

    a ballasted emission structure;

    a conductive column being formed on the ballasted emission structure; and

    an aperture being formed through the conductive column, the ballasted emission structure, and the non-conducting amorphous carbon layer thereby forming an emitter well and thereby exposing an emission edge of the ballasted emission structure being disposed within the emitter well and being emissive when exposed to an electric field having a field strength less than 150 volts/micrometer.
