Acquisition of Surface Electron Spectroscopy Instrumentation

该奖项旨在为华盛顿州立大学从事先进材料研究领域的教职员工和学生提供表面电子能谱仪器。具体要求的仪器是一台电子能谱仪（ES），结合了俄歇电子能谱仪（AES）、x射线光电子能谱仪（XPS）和紫外光电子能谱仪（UPS），包括必要的真空系统、电子设备和数据采集/数据显示系统。该设施将提供华盛顿州立大学目前没有的新能力。受益于该仪器的研究包括薄膜合成和加工、表面改性、激光表面相互作用、摩擦学和断裂，以及在原子水平上表征材料。AES/XPS可以进行定性和半定量的表面成分分析，并结合UPS，提供有关电子和化学结构的关键信息。华盛顿州立大学的一个关键要求是，设备既可以直接用于实验，也可以用于常规的表面分析。为了实现这一双重目的，我们将购买一个完整的光谱仪，该光谱仪具有两个负载锁定样品导入端口和温度控制样品台。由于许多用户需要在受控环境中进行独特的真空实验和/或样品制备和处理，我们将建立一个灵活的实验/样品制备处理室，连接到主分析室。第二个腔室的使用将安排在大时间段（约3-5周），以允许不同的用户清洁，配置和使用该系统，以达到他们的最佳优势。这种组合允许在特高压条件下进行实验，生长研究和/或原位样品制备以及伴随的表面分析。同时，在没有冲突的情况下，样品可以从外部引入分析室进行常规分析。获得这种能力对于大学内许多部门的研究活动至关重要，包括物理、化学、机械和材料工程、地质、化学工程和电气工程。这个活动是由两个跨学院组织组织的。材料研究中心和材料科学计划最近成立，以解决材料科学的跨学科性质。材料研究中心由来自6个不同部门的20名高级参与者组成，旨在鼓励材料科学与工程以及应用凝聚态科学领域的跨学科合作项目。材料科学项目是华盛顿州立大学材料科学专业的研究生教育部门；该项目于1990年秋季启动，是该大学最近创建的博士项目。在以下项目中，共有21名研究生和博士后，他们的研究将直接受益于该ES系统的获得。另外还有12名学生参与了本提案中描述的其他项目，他们的研究将从这些表面分析技术中显著受益。预计其他研究生和教师将被吸引使用该仪器一旦获得和演示。AES/XPS系统还将为研究生和本科生的教学工具提供实质性的好处，影响至少10名学生。

9503304 Dickinson This award is for the acquisition of surface electron spectroscopy instrumentation to serve a number of faculty and students at Washington State University who are working in the area of advanced materials research. The specific instrumentation requested is an electron spectrometer (ES), combining an Auger Electron Spectrometer (AES), X-Ray Photoelectron Spectrometer (XPS), and Ultraviolet Photoelectron Spectrometer (UPS), including the necessary vacuum system, electronics, and data acquisition/data presentation system. This facility will provide new capabilities at Washington State University not presently available. The research that will benefit from this instrumentation includes efforts in thin film synthesis and processing, surface modification, laser surface interactions, tribology and fracture, and characterization of materials on an atomic level. AES/XPS allows both qualitative and semiquantitative analysis of surface composition and, combined with UPS, provides critical information about electronic and chemical structure. A key requirement at WSU is that the facility be configured for both direct use by experiments and for routine surface analysis. To achieve this dual purpose, we will purchase a complete spectrometer with two load lock sample introduction ports and temperature controlled sample stage. Because many of the users require unique vacuum experiments and/or sample preparation and treatment in a controlled environment, we will build a flexible experimental/sample preparation treatment chamber to be attached to the main analysis chamber. The use of this second chamber will be scheduled in large time blocks (about 3-5 weeks) to allow different users to clean, configure, and use this system to their best advantage. This combination allows the capability of performing experiments, growth studies, and/or in situ sample preparation with accompanying surface analysis under UHV conditions. Simultaneously, without conflict, samples can be introduced into the analysis chamber from the outside for routine analysis. Acquisition of this capability is essential for research activities in a number of departments within the University, including Physics, Chemistry, Mechanical and Materials Engineering, Geology, Chemical Engineering, and Electrical Engineering. This activity is organized under two crosscollege organizations. The Center for Materials Research and the Materials Science Program have been recently established to address the interdisciplinary nature of Materials Science. The Center for Materials Research consists of 20 senior participants from 6 different departments and was formed with the purpose of encouraging collaborative, crossdisciplinary projects in the area of materials science and engineering and applied condensed matter science. The Materials Science Program is the graduate educational arm of the materials science thrust at Washington State University; the Program was initiated in the Fall of 1990 and is the most recently created Ph.D. program in the University. In the projects described below there are a total of 21 graduate and postdoctoral students whose research will directly benefit from the acquisition of this ES system. There are an additional 12 students involved in other projects described in this proposal whose research would significantly benefit from these surface analysis techniques. It is anticipated that other graduate students and faculty will be attracted to use this instrumentation once it is acquired and demonstrated. The AES/XPS system would also provide substantial benefit as an instructional instrument for both graduate and undergraduate students impacting at least 10 additional students.
