Abstract

Field emission measurements using 0.3 mm thick nitrogen containing hydrogenated amorphous carbon films ~a-C:H:N! on n11-Si cathodes are reported. Onset emission fields as low as 4 Vmm21 have been obtained using a flat plate anode configuration. Uniform emission is observed over the entire cathode area at current densities below 731022 mA cm22. At higher current density preferential emission from spots is observed. The spot emission is imaged using the ITO coated plate anode. A model based on the a-C:H:N acting as a space charge interlayer on the n11-Si is proposed to explain the emission at low electric fields.
