Abstract: An array of carbon-based emitters is provided having more uniform electron emission over the area of the array. This is made possible by a resistive layer that is present below each of the emission tips. Both organic and inorganic resistive layers may be grown under the emitting carbon-based material. A conductive backing layer is in contact with the resistive layer. Methods for making the improved array are provided. The methods include growth of carbon-based tips in a mold, removal of various films or portions of films by etching, and other techniques.
