Abstract

A newly fabricated T-shape disk-edge field emitter is considered in the present paper. Numerical results are presented for a unit cell, consisting of emitter, gate, and anode. A new algorithm, Finite-Difference Method in Non- Orthogonal Curvilinear Coordinate System, is used for the calculation of electrostatic field. With the boundary- conforming coordinate lines, this method deals with microemitter shapes sufficiently. The dependence of field enhancement factor and emitted current upon geometrical factors and I-V characteristics are shown out. Several suggestions are given out for the geometry determination in fabrication.
