摘要：

An unambiguous comparison for magnification factor M in field emission is derived by solving rigorously Laplace equations for the cases of individual prolate ellipsoids (cones) of revolution on one, and for an elliptical wedge on the other side, under the assumption that a uniform electric field E0 exists at some distance away from the emitting surfaces. Significant superiority of M for individual emitters with rotational symmetry is demonstrated as compared to the wedge. Also discussed is the case of a "floating" sphere.
