摘要
利用射频磁控溅射技术在玻璃衬底上沉积ZnO-0.25mol%V_2O_5(ZnO∶V)薄膜,研究了O_2/(O_2+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(V_O)和间隙锌(Zn_i)杂化形成的复合体,两者比例随O_2/(O_2+Ar)流量比而变化。
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 V0 and Zni. And the ratio of Vo to Zni changed with the 02/(O2 + Ar) ratio.
