This tool can be used to evaluate the value of (k); a special mathematical function in field electron emission theory that presents the power of the voltage in the Murphy-Good plots.
Murphy-Good plots are the most recent and recommended methodology to test and analyse the field electron emission data (which is characterised by the obtained current-voltage or the macroscopic current density-field data). This type of plots take the form of ln(I/V^k) vs 1/V.
