| 摘 要： | 空气中的氧在CdS-CdSe烧结膜中晶粒表面上的吸附,使晶粒的表面态发生变化,影响了晶粒中载流子的表面复合率.直流光电导衰退法测量结果表明.氧的吸附增大了CdS-CdSe薄膜中载流子的表面复合率,从而使少数载流子的有效寿命下降.

| Abstract: | The Oxygen adsorption on the sintered CdS-CdSe polycrystallite films in the air changes the surface states of the crystallites in the films, and increases the surface recombination rate. The experiment shows that the oxygen adsorption on the film results the decrease of the effective minority carrier lifetime. |
