Code for evaluation of the field to thermo-field to
thermionic electron emission current
The code realizes the method
[1], which employs the Murphy-Good theory, relies on Padé
approximants and is computationally
efficient in the full range of conditions
of validity of the theory, from field to thermo-field to
thermionic emission regimes.
