Abstract

We fabricated graphite nanoplatelet (GNP) field emitters using graphite adhesive and graphite rod. Comparing the field emission properties for different gap, turn-on electric field and threshold electric field were decreased almost in half, and maximum current density was increased about half as many again. The long-term emission stability also shows better results in large gap more than small gap. We consider that it is due to decreased effects of local vacuum and outgassing in spite of high local electric field. These properties indicate that GNP field emitters could be robust field emitters.
