Abstract
High current field emission cathodes containing nanomaterials, and methods for their production, are provided. An exemplary method comprises forming an electrically resistive layer on a cathode substrate, forming an adhesion promoting layer on the electrically resistive layer, and forming an electron emissive layer including nanomaterials on the adhesion promoting layer. Forming each layer can include depositing a suitable mixture followed by a heating process including three firing cycles. Deposition can be performed by electrophoretic deposition or a printing technique. The layers can be patterned to form islands separated by well-defined gaps on the substrate.
