1. A method of making a field emitter device, comprising the steps of:

  • providing a substrate;

    depositing a layer of a low effective work function material on said substrate;

    depositing a first layer of a conductive material in a first location near said layer of said low effective work function material; and

    depositing a second separate layer of said conductive material in a second location near said layer of said low effective work function material, said first and second locations positioned relative to each other and to said layer of said low effective work function material so that said first and second layers of said conductive material are operable to produce an electric field across a surface of said layer of said low effective work function material when a voltage potential is applied between said first and second layers of said conductive material.
