项目摘要
The objective of this CAREER project is a comprehensive education and research program aimed at the development of next-generation devices using functional perovskites by providing atomic-level understanding of interface properties relevant for practical applications. Materials science research will be pursued research toward: (a) mixed ionic-electronic conducting (MIEC) perovskite oxides for electrochemical devices, and (b) ferroelectric thin films for capacitors and microelectromechanical systems (MEMS). In these devices, interface structure and properties play a key role in determining materials and device properties. Providing a fundamental understanding of transport mechanisms across interfaces will enable more energy-efficient, cost-effective devices, and aid the design of thin film electrochemical devices. Ferroelectric perovskites have a host of properties that enable further development of technologies such as microelectromechanical systems (MEMS). The physical properties of ferroelectric perovskite thin films are drastically different from those of bulk materials, for reasons that are currently poorly understood. Establishing the role of interfaces in observed behavior is expected to allow development of optimized microstructures for applications in MEMS and electronic devices. The method developed in this project will concentrate on interfaces with known atomic arrangements and defect chemistry. These will be obtained by controlled thin film growth experiments and by utilizing unique capabilities of high-resolution transmission electron microscopy in combination with electron energy-loss spectroscopy. Macroscopic measurements of transport properties of oxide interfaces and of the physical behavior of ferroelectric thin films is being studied to establish fundamental limits of interfacial properties, relevant for all applications of functional perovskites. In addition, this research is intended to set the stage for atomic level calculations that will need the true atomic structure as input. Part of the research on thin film electrochemical devices will involve an established collaboration with industry, as well as interdisciplinary research with national and international university researchers in the areas of electrochemical transport and electrical characterization. An important feature of the project is the training of students in interdisciplinary, industrial and international collaborative activities, in technologically important research areas. A main goal of the project is to thoroughly integrate research into educational activities. Emphasis will be placed on (a) participation of undergraduate students in research early in their studies (b) interdisciplinary and international training, and (c) mentoring of students of underrepresented groups with the goal to encourage them to pursue graduate studies in materials science and engineering. Course development plans include strengthening the core curriculum to emphasize conceptual understanding of the course material for a broad interdisciplinary audience, and to incorporate new technologies. Conceptual testing as a method to evaluate the success of the educational activities will also be developed.%%% 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. ***
这个职业项目的目标是一个全面的教育和研究计划,旨在通过提供与实际应用相关的界面属性的原子水平的了解,开发使用功能钙钛矿的下一代设备。材料科学研究将在以下方面进行:(A)用于电化学设备的混合离子-电子导电(MIEC)钙钛矿氧化物,以及(B)用于电容器和微电子机械系统(MEMS)的铁电薄膜。在这些器件中,界面结构和性能在决定材料和器件性能方面起着关键作用。通过对界面传输机制的基本了解,可以实现更节能、更具成本效益的器件,并有助于薄膜电化学器件的设计。铁电钙钛矿具有许多特性,使诸如微型机电系统(MEMS)等技术的进一步发展成为可能。由于目前尚不清楚的原因,铁电钙钛矿薄膜的物理性质与块体材料的物理性质有很大的不同。确定界面在观察到的行为中的作用有望为MEMS和电子设备中的应用开发优化的微结构。这个项目中开发的方法将集中在具有已知原子排列和缺陷化学的界面上。这将通过受控薄膜生长实验和利用高分辨率透射电子显微镜与电子能量损失光谱相结合的独特能力来获得。目前正在研究氧化物界面的输运性质和铁电薄膜的物理行为的宏观测量,以确定与功能钙钛矿的所有应用相关的界面性质的基本极限。此外,这项研究旨在为需要真实原子结构作为输入的原子级计算奠定基础。薄膜电化学装置研究的一部分将涉及与工业界的既定合作,以及与国内和国际大学研究人员在电化学传输和电特性领域的跨学科研究。该项目的一个重要特点是在重要的技术研究领域对学生进行跨学科、工业和国际合作活动的培训。该项目的一个主要目标是将研究彻底融入教育活动。重点将放在:(A)本科生在学习初期参与研究;(B)跨学科和国际培训;(C)对代表性不足群体的学生进行辅导,以鼓励他们攻读材料科学和工程方面的研究生课程。课程开发计划包括加强核心课程,以强调广大跨学科受众对课程材料的概念性理解,并纳入新技术。还将开发概念测试作为评估教育活动成功的方法。%该项目解决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在材料合成、加工和表征方面面临挑战。该项目的一个重要特点是高度重视教育,并将研究与教育相结合。***
