Acquisition of a Multi-technique Surface Analysis System

9512264多伊尔将由阿拉巴马大学塔斯卡卢萨分校获得一套多技术表面分析系统，初步具备X射线光电子能谱和扫描俄歇显微镜的能力。这种基本能力目前在塔斯卡卢萨校区不存在，是该大学对其材料科学项目的承诺的一部分。这些设备将放置在中央分析设施中，为该大学的主要材料研究项目服务，最著名的是信息技术材料中心(MINT)。铸币厂是一项多学科研究计划，专注于柔性磁性介质和磁头的新材料，这两个领域将直接受益于SAM/XPS的力量。XPS和SAM在一个仪器中的组合允许确定近表面化学成分(SAM)和组成梯度(SAM)、深度剖析(SAM)、化学键(XPS)、化学状态(XPS)和官能团(XPS)。该仪器将支持高磁化和高矫顽力薄膜和颗粒、磁性三层结构中的耦合、多层结构中的巨磁电阻、磁性介质的磨损和腐蚀以及金属基复合材料等研究项目。多技术表面分析系统将满足校园内几个材料研究项目的基本需求，因此将对学术基础设施产生重大影响。它将允许教师提出更全面的、因此更具竞争力的材料研究提案，并将为学生提供实践培训和最先进的工具。该仪器还将扩大与工业赞助商合作研究的机会。***

9512264 Doyle A multi-technique surface analysis system with initial capability for X-ray photoelectron spectroscopy (XPS) and scanning Auger microscopy (SAM) will be acquired by the University of Alabama-Tuscaloosa. This fundamental capability does not now exist at the Tuscaloosa campus and is part of the University commitment to its materials science program. The equipment will be located in a central analysis facility which serves major materials research programs at the University, most notably the Center for Materials for Information Technology (MINT). The MINT is a multidisciplinary research program focusing on new materials for flexible magnetic media and heads, two areas in which the power of SAM/XPS will be directly beneficial. The combination of XPS and SAM in one instrument allows for the determination of near surface chemical composition (SAM) and composition gradients (SAM), depth profiling (SAM), chemical bonding (XPS), chemical states (XPS), and functional groups (XPS). The instrument will support research programs in high magnetization and high coercivity films and particles, coupling in magnetic trilayer structures, giant magnetoresistance in multilayered structures, wear and corrosion of magnetic media, and metal matrix composites, among others. %%% The multi-technique surface analysis system will fulfill a fundamental need of several programs in materials research on campus and will thus have a large impact on the academic infrastructure. It will allow faculty to propose more comprehensive, and therefore more competitive, materials research proposals, and will provide students with hands-on training with a state-of-the-art tool. This instrument will also expand opportunities for cooperative research with industrial sponsors. ***
