Abstract
In this article, a new numerical algorithm, a finite-difference method in a nonorthogonal curvilinear coordinate system, is presented. This algorithm can be used for efficient simulation of a disk-edge held emi tter. With the boundary-conforming coordinate lines, this method can d eal with arbitrary microemitter shapes. Simulation results are present ed for a unit cell, consisting of a disk-edge field emitter with ''coc ktail glass'' structure. Dependence of the field enhancement factor, e lectron trajectories, and emission current upon geometrical factors ar e presented. (C) 1997 American Vacuum Society.
