Calculation of diode system with ellipsoidal field emitter


In this graduate qualification work axisymmetric diode system based on field emitter is modeled. Maslova T.A. represented mathematical models for the two diode systems. The first diode system consists of a field cathode on a flat substrate and an anode. Surfaces of the cathode and anode are confocal ellipsoids of rotation. The geometrical parameters of the second diode system are identical to the first system, but for the whole of the inner region of the second system is divided into subareas with different dielectrics. The electrostatic potential distribution for the two models found analytically by variable separation method in the coordinates of a prolate ellipsoid of revolution.

In addition, T.A. Maslova presented the results of numerical calculations of the electrostatic potential distribution for two kinds of specific emission diode systems in C Sharp programming language. This work represents graphs for various diode systems specific parameters.
These graphs demonstrate the effect of the layers with different dielectric permittivity for the potential distribution in the entire inner area of the system.
