In the experiment of the angular distribution of the hot electrons emission , three - peaks and double - peaks emission of the hot electrons resulted from the multi - acceleration mechanisms are observed in our experiments 在超热电子发射的角分布实验研究中,发现由几种加速机制所支配的超热电子的三峰发射和双峰发射。
As compared with amorphous diamond on si , the reduction of the applied electric field for the electron emission can be effectively improved by using sm / amorphous diamond contact 我们发现非晶钻石长在镀钐的硅基板比单纯长在硅基板上的场发射特性更好,主要是因为金属有相对较低的功函数,可以降低金属钻石接面的位障高度。
Currently , cylinder2 - 1 / 2d includes boundary conditions for the electric and magnetic fields at the surface of ideal conductors , the cylindrical axis , the incoming wave ports . a new and simple model for explosion electron emission from cathode surfaces is described 程序中实现了多种边界条件,如良导体、对称轴、入射波等,详细地介绍了阴极表面爆炸发射电子的算法处理和程序实现。
Angular distribution and energy spectrum of the hot electrons emission resulted from the interaction of the us - ui laser pulse with plasma are measured with the calibrated lif tlds , and the yield of the hot electrons is consistent with the results of the other experiments 采用这样标定的l正tlds作为电子谱仪的探测元件,所测量的超热电子产额与国外同类实验测量的超热电子产额较好地一致。
In this paper based on the theory of the low energy electrons , the movement of the irons in the counter is analyzed . the theories of sputtering and secondary electron emission are discussed respectively . the irons " action and effect on the counter are putted forward 本文从低能电子发射机理入手,分析了计数管内部离子运动情况,讨论了离子溅射和二次电子发射,提出了离子与计数管内壁相互作用及其对计数管的影响,给出了计数管内壁表面处理仿真图。
