摘要

对不同聚焦结构的场发射器件进行了仿真。结果表明，同轴结构的聚焦效果最好，但阳极电流最低。脊型结构能提供最大的阳极电流，但聚焦效果较差。共面型结构除具有良好的聚焦效果外，还具有阳极电流适中和制造工艺最简单的优点。结果表明，共面型聚焦结构是显示应用的最佳选择。

Field emission devices with focusing structures

Field emission devices with different focusing structures are simulated. The results show that the coaxial-type structure gives the best focusing effect but with lowest anode current. The ridge-type structure could give the largest anode current but its focusing effect is poor. The coplanar-type structure, in addition to its good focusing effect, has a moderate anode current and the simplest fabrication process. It is concluded that the coplanar-type focusing structure is the best choice for display application.
