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
本文在深入研究真空微电子器件场致发射理论的基础上，根据圆锥形、楔形阴极真空微电子三极管的不同特点，分别建立了物理和数学模型，在考虑空间电荷密度影响的前提下，以有限元法为基础采用迭代的方法计算出真空微电子三极管内的电势分布情况，绘制出了等势线、电子轨迹线，并得到了器件电学性能随几何参数的变化情况。
