Abstract
This Poster outlines simple general derivations of the correction factors λ T =πp/sin(πp) and λ F =πq/sin(πq) that first appeared in this form in the 1973 re-formulation by Swanson and Bell of equations originally derived by Murphy and Good in 1956. The original proofs and results apply only to the Schottky-Nordheim barrier. For planar smooth-surface conceptual models, analyzed via the Kemble approach, the proofs outlined here apply to any barrier, provided that appropriate detailed (barrier-dependent) expressions can be found for the parameters p and q. An assessment of mathematical validity is reported on the Poster.
