导电薄膜功函数的确定在显示器件应用时起到至关重要的作用。随着基于石墨烯等新材料技术的柔性显示器的批量应用,准确测定石墨烯柔性导电薄膜功函数在产业化方面的需求越来越大。 目前为止主流的功函数测试方法是开尔文探针力显微镜(KPFM)法。该方法准确,且可同时获得测试范围内的材料形貌等信息,因此被市场广泛采用,用来测试上一代非柔性显示器件中氧化铟锡(ITO)玻璃的功函数。KPFM方法的缺点是测试时间相对较长,且测试范围较小,通常为几十至几百平方微米。 于石墨烯薄膜的缺陷度较高,因此功函数在膜片中的分布均匀性较ITO玻璃低。此时,光电子能谱法(UPS法)测试功函数的优点逐渐显现。首先,UPS法的最大测试范围可至2 mm╳2 mm,一定程度上规避了KPFM过于微观的特性。其次,UPS测试便捷、快速,可以在几分钟内得到测试结果。此外,UPS法还能同时得到样品的能带信息。 因此,UPS法测功函数可作为KPFM方法的有益补充。KPFM方法适用于对于研发等对微观精度要求高的场合,UPS方法可快速准确获得宏观薄膜的整体功函数情况,适用于批量交付产品中的质量控制。 本文件规范了UPS法测功函数的方法,以规范UPS法测功函数的基本操作,使此方法在以柔性显示器件为首的产业化进程中更好地发挥作用。

1.1 This practice sets forth requirements to ensure consistency in neutron-induced displacement damage testing of silicon and gallium arsenide electronic piece parts. This requires controls on facility, dosimetry, tester, and communications processes that affect the accuracy and reproducibility of these tests. It provides background information on the technical basis for the requirements and additional recommendations on neutron testing. 1.2 Methods are presented for ensuring and validating consistency in neutron displacement damage testing of electronic parts such as integrated circuits, transistors, and diodes. The issues identified and the controls set forth in this practice address the characterization and suitability of the radiation environments. They generally apply to reactor sources, accelerator-based neutron sources, such as 14-MeV DT sources, and 252 Cf sources. Facility and environment characteristics that introduce complications or problems are identified, and recommendations are offered to recognize, minimize or eliminate these problems. This practice may be used by facility users, test personnel, facility operators, and independent process validators to determine the suitability of a specific environment within a facility and of the testing process as a whole. Electrical measurements are addressed in other standards, such as Guide F980. Additional information on conducting irradiations can be found in Practices E798 and F1190. This practice also may be of use to test sponsors (organizations that establish test specifications or otherwise have a vested interest in the performance of electronics in neutron environments). 1.3 Methods for the evaluation and control of undesired contributions to damage are discussed in this practice. References to relevant ASTM standards and technical reports are provided. Processes and methods used to arrive at the appropriate test environments and specification levels for electronics systems are beyond the scope of this practice; however, the process for determining the 1-MeV equivalent displacement specifications from operational environment neutron spectra should employ the methods and parameters described herein. Some important considerations and recommendations are addressed in Appendix X1 (Nonmandatory information). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
