  1. With the use of finite method we have developed computer simulation software for vacuum microtriodes with wedge - shaped and cone - shaped cathode on the basis of stduying deeply the field emission theory of vacuum microelectronics. the software included field section, grid point numbering, and the calculation of electric currents, transconductance and cathode capacitance, moreover, it can simulate the properties of vacuum microeletronic with variant structures and sizes. the relationship was studied and simulated among electic properties and device structures, sizes and cathode materials etc. the optimized design of vacuum microtiode was proposed

    本文在深入研究真微電子器件場致發理論的基礎上,根據圓錐形、楔形陰微電子三體的不同特點,分別建立了物理和數學模型,在考慮電荷密度響的前提下,以有元法為基礎採用迭代的方法計算出真微電子三體內的電勢分佈情況,繪制出了等勢線、電子軌跡線,並得到了器件電學性能隨幾何參數的變化情況。
