英文: 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.
中文: 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。

英文: Based on the comparison and analysis of the secondary electron emission coefficient of two kinds of emitter GaAs in theory, it is concluded that when primary electron energy is lower the deviation of secondary electron emission coefficient of two kinds of
中文: 通过对两种负电子亲和势二次电子发射材料的二次电子发射系数的理论值进行比较和分析，得出：当原电子入射能量较低时，两种材料的二次电子发射系数差值较小；当原电子入射能量较高时，两种材料的二次电子发射系数差值较大，而且随着原电子入射能量的升高，两种材料的二次电子发射系数差值也在增大。
