This CAREER project addresses a comprehensive research and education study of functional thin-film metal-oxides based on combinatorial methods. The combinatorial approach will be used to survey large compositional variations in individual experiments. New materials phases will be explored through fabrication of thin-film combinatorial libraries and composition-spread samples. The method for fabricating samples is a newly designed combinatorial pulsed laser deposition system. Scanning probe microscopies will be used to perform rapid characterization of the samples. In particular, a scanning evanescent microwave microscope, a ferromagnetic reso-nance microscope and a scanning SQUID microscope will serve as the main screening tools. Sample quality will be addressed by using various microanalysis tools, which allow spatially re-solved composition and phase mapping. The immediate focus will be on microwave materials for wireless communications applications and various magnetic materials including ferrites and half-metallic systems. In addition to searching for new compositions with enhanced physical proper-ties, composition-spread experiments will be conducted to systematically study composition-property relationships in materials that had previously only been made in bulk samples. Experi-mental tasks required in the proposed program span fundamental materials synthesis to develop-ing novel characterization techniques, and this multidisciplinary research environment will serve as a model educational background to train a new generation of students.In collaboration with other faculty a lab-based Combinatorial Materials Research and Education Course using mostly preexisting equipment targeting senior-level undergraduates will be devel-oped. Many of the course activities will mirror the actual research techniques developed in the research activities, thus directly linking research with education. The ability of combinatorial ex-periments to rapidly cover a range materials with large compositional variation in a single ex-periment will be used to provide hands-on experience that conveys the breadth of materials sci-ence to students. The emphasis on "search and discovery" in combinatorial research makes this method particularly exciting and effective as an educational tool.%%% The project addresses fundamental research issues in a topical area of materials science having high technological relevance. The scope of the project will expose students to challenges in materials synthesis, processing, and characterization. An important feature of the project is the strong emphasis on education, and the integration of research and education. ***

该职业项目致力于基于组合方法的功能性薄膜金属氧化物的综合研究和教育研究。组合方法将用于调查单个实验中较大的成分变化。将通过制造薄膜组合库和成分扩散样品来探索新材料相。制备样品的方法是一种新设计的组合脉冲激光沉积系统。扫描探针显微镜将用于对样品进行快速表征。特别是，扫描倏逝微波显微镜、铁磁共振显微镜和扫描SQUID显微镜将作为主要筛选工具。样品质量将通过使用各种微量分析工具来解决，这些工具允许在空间上重新解析成分和相图。当前的重点将是用于无线通信应用的微波材料以及包括铁氧体和半金属系统在内的各种磁性材料。除了寻找具有增强物理性能的新成分外，还将进行成分扩散实验，以系统地研究以前仅在批量样品中制备的材料的成分与性能关系。拟议项目所需的实验任务涵盖基础材料合成到开发新颖的表征技术，这种多学科研究环境将作为培养新一代学生的示范教育背景。将与其他教师合作，开发基于实验室的组合材料研究和教育课程，主要使用针对高年级本科生的现有设备。许多课程活动将反映研究活动中开发的实际研究技术，从而将研究与教育直接联系起来。组合实验能够在一次实验中快速覆盖成分变化较大的一系列材料，从而为学生提供实践经验，从而向学生传达材料科学的广度。组合研究中对“搜索和发现”的强调使得这种方法作为一种教育工具特别令人兴奋和有效。%%% 该项目解决了具有高度技术相关性的材料科学主题领域的基础研究问题。该项目的范围将使学生面临材料合成、加工和表征方面的挑战。该项目的一个重要特点是高度重视教育，以及研究与教育的融合。 ***
