Figure 3From: Microplasma illumination enhancement of vertically aligned conducting ultrananocrystalline diamond nanorodsThe electron field emission properties of the N 2 -UNCD nanorods. Inset (a) shows the corresponding Fowler-Nordheim plot. Inset (b) shows the plasma illuminating current stability measurement of a microplasma cavity, which utilized the N2-UNCD nanorods as cathode and ITO glass as anode.Back to article page
