Test of field emission data using Murphy-Good coordinates for emitters based on carbon nanotubes

Developed test allows to determine the correspondence of the experimental data to the classical field emission dependence. The test uses the Elinson-Shrednik approximation to the current-voltage characteristics in the classical Fowler-Nordheim coordinates, as well as the modern Forbes-Deane approximation with modified Murphy-Good coordinates. We created the computerized experimental system for online calculation of the effective parameters of the emitters with stochastic analysis of its fluctuations and test the experimental data for correspondence to the classical field emission theory with fragmentation of the current-voltage curve. The application of the test was shown by the example of study of multi-tip field emitters based on carbon nanotubes.
