This CAREER project aims to develop a leading research and education activity in the area of metal/semiconductor growth, and self-organized pattern formation on surfaces. Through integra-tion of innovative research with a broad education and outreach effort, the project expects to dramatically advance fundamental understanding of organic and inorganic thin-film growth and etching kinetics. A series of experiments are aimed at producing methods of controlling the structure of thin films for the next generation of devices in several materials systems related to information technology. Key areas include: (i) Kinetics of pulsed laser Molecular Beam Epitaxy. Important issues are the formation and ultimate limits of non-equilibrium alloys, and the interplay of structure with carrier transport and magnetic properties. (ii) Patterning of surfaces by ion etch-ing. This research seeks methods for self-organized fabrication of nanostructured thin films and control of the structure of interfaces between materials. (iii) Organic electronics, where it is of paramount importance to understand the interplay of crystalline structure and thin film growth kinetics with electrical properties and stability/reliability. The three research areas have a common intellectual theme through greater understanding and development of complementary thin film materials for applications in optoelectronics, magneto-electronics, spintronics, and low cost electronics. %%%The project addresses fundamental research issues in electronic materials science having technological relevance. The research plan is closely integrated with an energetic education and outreach program incorporating extensive mentoring. New courses will be developed to provide un-dergraduate and graduate students with a solid background in x-ray physics, materials science, and nanotechnology. In addition to graduate research assistants, undergraduate students will be involved in the research program, providing them with valuable opportunities to complement their theoretical training. Students at all levels will be encouraged to present results at national meetings. A greater community focusing on thin film electronic materials is envisioned from diverse groups across the campus and at other colleges, universities, national laboratories, and local industry, which will give students the opportunity to experience a multidisciplinary environment. The program will make use of the multi-user facility for X-ray Studies of Materials with Analysis in Real-Time (X-SMART) at the National Synchrotron Light Source (NSLS), as well as facilities at the University of Vermont and at Cornell University. An extended outreach program aimed at K-12 students and teachers, female/minority colleges, and industry, will build on the Vermont HELIX program, extending these benefits to rural Vermont and inner city New York schools. This project will benefit society by creating new knowledge in an important area of science re-lated to modern technology, by producing highly skilled workers for related industries, and by raising the level of community interest in science and technology. ***

该职业项目旨在在金属/半导体生长和表面自组织图案形成领域开展领先的研究和教育活动。通过将创新研究与广泛的教育和推广工作相结合，该项目预计将极大地增进对有机和无机薄膜生长和蚀刻动力学的基本理解。一系列实验旨在产生控制薄膜结构的方法，用于与信息技术相关的几种材料系统中的下一代器件。关键领域包括： (i) 脉冲激光分子束外延动力学。重要的问题是非平衡合金的形成和最终极限，以及结构与载流子传输和磁性的相互作用。 (ii) 通过离子蚀刻对表面进行图案化。本研究寻求自组织制造纳米结构薄膜和控制材料之间界面结构的方法。 (iii) 有机电子学，了解晶体结构和薄膜生长动力学与电性能和稳定性/可靠性之间的相互作用至关重要。这三个研究领域有一个共同的知识主题，即通过更好地理解和开发用于光电子学、磁电子学、自旋电子学和低成本电子学应用的互补薄膜材料。 %%%该项目解决了具有技术相关性的电子材料科学的基础研究问题。该研究计划与充满活力的教育和推广计划紧密结合，并提供广泛的指导。我们将开发新课程，为本科生和研究生提供 X 射线物理、材料科学和纳米技术方面的扎实背景。除了研究生研究助理外，本科生也将参与研究计划，为他们提供宝贵的机会来补充他们的理论培训。将鼓励各级学生在全国会议上展示成果。校园内以及其他学院、大学、国家实验室和当地工业界的不同群体设想建立一个专注于薄膜电子材料的更大社区，这将使学生有机会体验多学科环境。该计划将利用国家同步加速器光源 (NSLS) 的多用户设施进行材料 X 射线研究实时分析 (X-SMART)，以及佛蒙特大学和康奈尔大学的设施。针对 K-12 学生和教师、女性/少数族裔大学和行业的扩展外展计划将以佛蒙特州 HELIX 计划为基础，将这些好处扩展到佛蒙特州农村和纽约市中心的学校。该项目将通过在与现代技术相关的重要科学领域创造新知识、为相关行业培养高技能工人以及提高社会对科学技术的兴趣水平来造福社会。 ***
