Comparison of the Lepetit Field emission currentdensity calculations with the Modinos-Forbes uncertainty limits

This poster makes some preliminary comparisons between (a) the results of atomic-level theories of metal field electron emission (FE) recently reported by Lepetit, and (b) the Modinos-Forbes uncertainty limits relating to the accuracy of zero-temperature Murphy-Good theory (which is based, like most existing FE theory, on an unrealistic smooth-surface conceptual model). It is found that there is broad consistency between the new results and the old uncertainty limits. The poster briefly indicates some further steps that would now be useful, on the long and winding path towards developing accurate and reliable field emission theory.
