摘要:
分析钙钛矿薄膜的制样方法、测试位置和基底材料等对紫外光电子能谱(UPS)的影响,提出减小电子传输距离以增强UPS响应的策略.结果表明:相比钙钛矿上表面与样品台连接的样品,部分裸露钙钛矿层下方的导电基底与样品台连接的样品能够增强UPS响应;“ITO-胶带法”样品具有纵向电子传输特征,UPS测试结果几乎不受测量位置影响,有最强的UPS响应;“ITO-对比样”样品的测量位置需要靠近铜导电胶带才能减小电子传输距离,从而获得更佳的UPS响应.
Abstract:
The influences of sample preparation methods,testing locations and substrate materials of perovskite thin films on ultraviolet photoelectron spectroscopy(UPS)were analyzed,and a strategy of reducing electron transfer distance to enhance UPS response was proposed. The results showed that,compared to the samples connected to the upper surface of perovskite and the sample stage, the samples connected to partially exposed conductive substrate below perovskite layer and the sample stage could enhance UPS response. The “ITO-tape method” samples presented longitudinal electron transmission characteristics,and the UPS testing results were almost not affected by measurement location,showing the best UPS response. In order to obtain better UPS response,the measurement position of the “ITO-comparison sample” samples needed to be close to the copper conductive tape to reduce the electronic transmission distance.
