MRI: Acquisition of a Near Ambient Pressure X-ray Photoelectron Spectroscopy System to Enable Active Near-Surface and Interface Analysis

非技术：传统的x射线光电子能谱（XPS）提供了超高真空条件下表面和界面的化学、分子、电子和成分性质的基本信息。近环境压力XPS （NAP-XPS）通过在接近大气压的背景气体存在下进行分析，大大扩展了传统XPS科学探究的深度和广度。NAP-XPS系统将加强俄勒冈州立大学（OSU）和西北太平洋地区科学和工程界的跨学科研究和教育项目。该系统将作为俄勒冈州立大学材料合成与表征（MaSC）设施的一部分进行操作和管理，该设施是面向所有学术、政府和工业实验室的研究人员的开放用户资源。与周六学院和俄勒冈州立大学的教育合作伙伴计划合作，主要研究人员将为中学生和教师提供新的暑期科学营和研讨会，涵盖能源和材料研究的当前主题。这些努力将扩展到公共非正式教育项目，包括材料、化学、物理、工程、社区和可持续性方面的最新研究进展。技术：材料、器件和加工的跨学科研究为许多科学和工程领域的活动提供了知识基础，包括材料合成、催化、能量转换、电子器件以及生物和环境传感。NAP-XPS对表面和界面的详细化学、分子和成分的理解提供了对复杂系统的独特见解，并指导了材料、设备和加工科学的改进。NAP-XPS具有太平洋西北地区其他地方无法获得的能力。该仪器将能够测量压力范围超过11个数量级（5x10-10至20mbar）的XPS光谱，样品温度在200至723 K之间。该系统将加强跨材料科学、化学、物理、化学工程和电气工程的合作项目和计划。研究领域包括通过溶液和真空方法制备的模型催化、光学、压电和电子材料的合成和研究；确定了分压和温度对探针分子在模型催化体系上吸附状态的影响；评价最先进的直接图案无机硬膜的热刺激过程；电子和光电子器件的光谱学，包括与太阳能电池和金属-绝缘体-金属二极管有关的界面的带对准；以及用于电子和光电应用的薄膜和纳米材料的功能化和缺陷钝化。

Non-technical:Conventional X-ray photoelectron spectroscopy (XPS) provides fundamental information on chemical, molecular, electronic, and compositional properties of surfaces and interfaces under ultra-high vacuum conditions. Near ambient pressure XPS (NAP-XPS) significantly extends the depth and breadth of scientific inquiry of conventional XPS by enabling analyses in the presence of a background gases near atmospheric pressures. The NAP-XPS system will enhance interdisciplinary research and education programs throughout the scientific and engineering communities at Oregon State University (OSU) and the Pacific Northwest. The system will be operated and managed as part of the Oregon State University Materials Synthesis & Characterization (MaSC) Facility, an open user resource for researchers from all academic, government, and industrial laboratories. In partnership with Saturday Academy and the Education Partnerships Program at OSU, the principle investigators will offer for middle school students and teachers new summer science camps and workshops covering current topics in energy and materials research. These efforts will be extended to public informal education programs, encompassing the latest research advances in Materials, Chemistry, Physics, Engineering, Community, and Sustainability.Technical:Interdisciplinary research in materials, devices, and processing provides the knowledge base to advance activities in many scientific and engineering fields, including materials synthesis, catalysis, energy conversion, electronic devices, and bio and environmental sensing. The detailed chemical, molecular, and compositional understanding of surfaces and interfaces enabled by the NAP-XPS provides unique insight into complex systems and guides improvements in material, device, and processing sciences. The NAP-XPS has capabilities that are not available elsewhere in the Pacific Northwest. The instrument will enable measurement of XPS spectra covering pressure ranges over 11 orders of magnitude (5x10-10 to 20 mbar) and sample temperatures between 200 and 723 K. This system will enhance collaborative projects and programs across material science, chemistry, physics, chemical engineering, and electrical engineering. Areas of research include the synthesis and study of model catalytic, optical, piezoelectric, and electronic materials prepared by solution and vacuum-based methods; determining the role of partial pressure and temperature on adsorption state of probe molecules on model catalytic systems; evaluating thermal-stimulated processes for state-of-the-art directly patterned inorganic hardmasks; spectroscopy of electronic and optoelectronic devices including band-alignment for interfaces related to solar cells and metal-insulator-metal diodes; and functionalization and defect passivation of thin films and nanomaterials for electronic and optoelectronic applications.
