Using numerical simulations based on finite-element techniques, this work investigates the electrostatic interaction (“mutual shielding”) between two emitters each modeled as a cylindrical post capped with a hemisphere (the “HCP” model). The interaction between two adjacent emitters has recently been investigated in [8, 11], using different models. Reference [8] used the (analytical) “floating spheres...
This Poster outlines simple general derivations of the correction factors λT=πp/sin(πp) and λF=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,...
