Abstract :
Summary form only given. A modified volcano-shaped field emitter has been proposed and is being studied using MAGIC particle-in-cell simulation code. This new structure consists of a volcano-shaped field emitter tip, a volcano-shaped gate, and a planar anode. In this paper, the dependence of the emission current density distribution upon geometrical factors, for example, rim sharpness of the emitter, rim radii of the gate and the emitter, and the distance between the gate and the rim of the emitter, will be presented. The emission characteristics of this modified volcano-shaped field emitter will be compared with the conventional volcano-shaped field emission microtriodes with con-shaped emitters.
