An engineering ansatz for rescuing “waste-bin” field emission results

This conference poster presents an engineering ansatz that may be useful in situations where an orthodoxy test on the related Fowler-Nordheim plot has suggested that an extracted apparent field enhancement factor (FEF) β^app is spuriously large. The ansatz, called phenomenological adjustment, converts β^app to a smaller “ansatz-corrected” value β^azc that can be presumed to be closer to the true macroscopic FEF (γ_C) value.
