Abstract:

Several gated field emitter-on-a-column structures with low capacitance and improved gate-emitter isolation have been successfully fabricated. Testing has indicated additional effort is required to improve transconductance. Variations of the above columns with sharper points are in process. Samples of our column emitters, standard emitters, and flat gated cathodes have been sent to several vendors for diamond and diamond-like depositions. New vacuum test systems for field emitters have just been constructed at NCSU and UNC-Charlotte. Field-ion micrographs and electron emission patterns have been studied for our emitters under a variety of conditions. Amplifier modules containing our gated emitters have been constructed.
