Cold field electron emission (CFE) is an electron emission regime where electrons are field emitted from a surface, by tunneling from states near the emitter Fermi level (Forbes, 2012; Forbes et al., 2015). The emission process is controlled by the height and width of the surface potential-energy (PE) barrier, and the barrier width is determined by the magnitude F of the local barrier electrostatic field. For metal emitters, the emission current I from a single tip emitter is given by a Fowler-Nordheim-type (FN-type) equation (Forbes, 2012; Forbes et al., 2015):
