利用射频麟控溅射法在石英玻璃衬底上制备ZnO:Ga透明导电氧化物薄膜,主要研究了一种类调制掺杂工艺对GZO薄膜的薄膜形貌结构和光电性能的影响。通过X射线衍射仪(XBD)、扫描电子显微镜(SEM)、紫外-可见-近红外分光光度计(UV-VIS-NIR)和四探针测试仪对GZO薄膜进行表征。结果表明:不同的衬底温度调制下生长的GZ0薄膜都具有明显的C轴择优取向,对于衬底温度调制条件下,在150℃/RT条件下的薄膜结晶最好,且在可见近红外波段(480~1600nm)平均透过率达到85.4%左右,薄膜最低方阻达到60Ω/□。
Transparent conductive GZO oxide films were prepared on quartz glass substrate using radio-frequency (RF) magnetron sputtering. The effect of a kind of new doping process on morphology structure and photoelectric properties of GZO films were investigated. The GZO thin films were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), ultraviolet-visible-near infrared spectrophotometer (UV-VIS-NIR) and four point probe resistance tester. The r~ults shows that all the GZO films prepared with different substrate temperatures have obvious C axis preferred grain orientation. Among the different substrate temperatures, the film crystallization is the best under the condition of 150℃ / RT, and the average transmittance of the film in visible and near infrared region(480 nm to 1600 nm) is about 85.4%, minimum sheet resistance reached 60Ω/□.
