This repository contains evaluations based on various theoretical models for calculating the emission current and Nottingham heating of a metal surface with a specified work function, temperature and applied electric field.
Includes the following models:
- direct integration
- Fowler-Nordheim
- Richardson-Schottky
- Jensen's general thermal-field
The following figure shows the emission current for copper surface with work function of 4.5 eV.
The following figure shows the Nottingham delta E (average energy of emitted electrons w.r.t. Fermi) for a copper surface with work function of 4.5 eV.
