用紫外光电子能谱和X射线光电子能谱研究了铝掺杂氧化锌(AZO)表面处理，即丙酮溶剂清洗和紫外光(UV)臭氧清洗对功函数的影响。比较不同的清洗方法，UV-臭氧处理的AZO的功函数相对较高，为4.26 eV，而丙酮溶剂处理的AZO的功函数相对较低，为3.94 eV。[OZnAl]/[Zn]+1.5[Al]的化学计量比和AZO表面的碳污染两个因素对功函数有影响，并且化学计量比是控制因素。结果表明，化学计量比高、碳浓度低的AZO具有较高的功函数。
The dependence of aluminum-doped zinc oxide (AZO) work function on surface treatment, i.e. acetone solvent cleaning and ultraviolet (UV)-ozone cleaning, was studied by ultraviolet photoelectron spectroscopy and X-ray photoelectron spectroscopy. Comparing different cleaning methods, UV-ozone treated AZO achieved relative higher work function of 4.26eV; whereas acetone solvent treated AZO had relative lower work function of 3.94eV. Two factors, stoichiometry ratio of [OZnAl]/[Zn]+1.5[Al] and carbon contamination on AZO surface, affected the work function and, moreover, the stoichiometry ratio was supposed to be the controlling factor. It was concluded that AZO with high stoichiometry ratio and reduced carbon concentration possessed high work function.
