Such a thin layer of LiF cannot efficiently protect the underlying active layer from damage during the evaporation of hot cathode metal atoms, and also cannot provide sufficient protection against the diffusion of oxygen and water. 如此薄的LiF不足以保护活性层在蒸镀金属电极时免受高温金属原子的破坏,也不能有效地阻挡氧气和水分子扩散进入活性层。
One of the hot topics of interaction between light and atoms is the electromagnetically induced transparency. 对于光与原子相互作用研究的热点之一就是电磁感应透明。
