O2/(O2+Ar)流量比对ZnO-0.25mol% V2O5薄膜缺陷类型的影响
Effect of O2/(O2+ Ar) Ratios on the Type of Defects in ZnO-0. 25mol% V2O5 Thin Films
【摘要】 利用射频磁控溅射技术在玻璃衬底上沉积ZnO-0.25mol%V2O5(ZnO∶V)薄膜,研究了O2/(O2+Ar)流量比(0%87.5%)对ZnO∶V薄膜中缺陷的影响。研究结果表明:沉积的ZnO∶V薄膜为具有c轴取向的纤锌矿结构,V以五价和四价形式共存其中。ZnO∶V薄膜中的缺陷态为氧空位(VO)和间隙锌(Zni)杂化形成的复合体,两者比例随O2/(O2+Ar)流量比而变化。
【Abstract】 ZnO-0. 25mol% Vanadium( ZnO ∶ V) thin films were deposited on glass substrate by RF magnetron sputtering. The type of defects in ZnO∶ V thin films under different O2/( O2+ Ar) ratios( 0%-87. 5%) was investigated. The deposited ZnO ∶ V thin films have wurtzite structure and show c-axis preferred orientation. V4 + and V5 + ions coexist in the films. The defect in ZnO ∶ V thin films is the complex of VO and Zni. And the ratio of VO to Zni changed with the O2/( O2+ Ar) ratio.
