摘要

美国宇航局路易斯研究中心在奥本大学制备的金刚石和类金刚石碳(DLC)薄膜上测量了二次电子产率。这些结果是海军水面作战中心发起的一项研究的一部分。金刚石薄膜的二次产率高达27;DLC薄膜的最大产率接近1.5。当受到持续的电子轰击时,金刚石膜的二次产率下降,但如果表面在真空中退火或暴露于氢气中,则可以恢复或增强发射。

Observations of secondary electron emission from diamond films
Secondary electron yields have been measured at NASA Lewis Research Center on diamond and diamond-like-carbon (DLC) films prepared at Auburn University. These results have been obtained as part of a study initiated by the Naval Surface Warfare Center. Secondary yields as high as 27 have been measured for the diamond films; the DLC films have maximum yields near 1.5. Secondary yields from the diamond films decline when they are subjected to continuous electron bombardment, but emission can be restored or enhanced if the surface is annealed in vacuum or exposed to hydrogen gas.<>
