Field emitter electrostatics: efficient improved simulation technique for highly precise calculation of field enhancement factors

HIGHLIGHTS

SUMMARY

    Computer simulations are becoming a ubiquitous tool to investigate characterization parameters in field electron emission (FE) systems. C. Methods for other shape models To apply either the MDD or the MDDET method to emittershape models other than the HCP, one inscribes the given shape into a hemi-ellipsoid. If the resulting mesh is "sufficiently fine," particularly near the apex of the chosen shape, then the meshing-error-magnitude can be made significantly less than the simulation-error-magnitude due to the proximity of the boundaries to the central post-like shape, and the former . . .
