在柔性衬底上制备透明导电薄膜ZnO:Zr
Semiconductor Technology（2009）
Abstract
采用射频磁控溅射法在室温柔性衬底PET上制备了掺锆氧化锌(ZZO)透明导电薄膜.利用不同方法提高了ZZO薄膜的电阻率而未使其可见光透过率降低.X射线衍射(XRD)和扫描电子显微镜(SEM)表明,ZZO薄膜为六角纤锌矿结构的多晶薄膜.在有机衬底和玻璃衬底上制备ZZO薄膜的择优取向不同,前者为(100)晶面,而后者为(002)晶面.在有ZnO缓冲层的PET衬底上制备的ZZO薄膜电阻率比直接生长在玻璃衬底样品上的小.通过优化参数,在PET衬底上制备出了最小电阻率为1.7×10-3Ω·cm、可见光透过率超过93%的ZZO薄膜.实验表明,镀膜之前在柔性衬底上沉积ZnO缓冲层能有效地提高ZZO薄膜的质量.
