Figure 4From: Field Emission and Radial Distribution Function Studies of Fractal-like Amorphous Carbon Nanotipsa SEM image of our FE set-up. The inset is the TEM image representative of the type of fractal nanorods tested; the scale bar is 200 nm.b FE current curve obtained at a distance of 252 nm and the inset is the linear FN plot.c Schematic representation of the three-stage model. Thesolid line corresponds to the first stage and so onBack to article page
