At low electric fields (less than 107 V/cm) the CV characteristics may be described by the FN formula for the emission current and can be used to estimate the effective barrier height, which is important in selecting a good cathode material.
One of the major characteristics of such vacuum nanodevices is the emission ability of this cathode, serving as a field emitter, that determined by the material of its coating and the presence of a thin natural oxide layer on its surface.
According to Eq. 13, the effective barrier height in the metal oxide layer also can be evaluated from the slope of the calculated CV characteristics, which is necessary for optimization of the cathode material.
