摘要
本文给出用新技术制作[Cs.Rb]Na_2KSb结构的光电阴极,具有灵敏度高、热发射低和重复性好等优点,特别是改善了光电器件的性能。并提出了四碱光电阴极的复合表面能带结构模型,对上述的实验结果给予了满意的解释。
A new fabrication technology of the multialkali photocathode of[Cs,Rb] Na_2KSb structure is reported. Photoelectronemissive mechanism of the photocathode films is discussed and a new structure model of energy bands at the surface-of [Cs,Rb]Na_2 KSb is proposed.
