In removing an electron from a metal, work has to be done against image-type forces. The classical image potential outside projections on an irregular surface is less than outside a plane surface but it is shown that the resulting lowering of the work function is entirely compensated by a patch field. Exact calculations cannot be made even for the single idealized surface projection for which image calculations are available. However, the axial patch potential for this case has been evaluated using an electrolytic tank and this shows that the form of the surface barrier is not affected by surface microgeometry.
