技术摘要：通过定向混合纳米结构的聚合物自组装程序，PI将对新型纳米结构非晶，多晶和单晶材料的合成，表征和结构-性能相关性进行研究，这些材料与其基底具有外延关系。网络形态的目标是从ABC三嵌段三元共聚物的自组装获得的，所述ABC三嵌段三元共聚物用作无机材料（包括氧化物、金属和半导体）的结构导向剂。该计划的目的是了解潜在的基本化学，热力学和动力学形成原理，使结果在更广泛的材料系统类的推广。该研究包括所有必要的有机/聚合物和无机成分的合成，使用各种散射和电子显微镜技术的组装结构的表征，具体性能的研究，以及光电器件的调查。跨学科性将是这项工作的一个主要特点。 该项目还将涉及与康奈尔大学和国外（英国剑桥和牛津大学）的几位具有互补专业知识的研究人员的广泛互动。非技术总结：PI提议研究成功纳米结构化的基本原理各种材料，例如氧化物、金属和半导体在特殊设计的聚合物的帮助下。 这些聚合物应该能够组装高度复杂的结构。 如果成功，该计划将在从微电子到能量转换和存储的广泛领域产生重大影响，通过新颖的方式将物质组织成具有以前不可用的功能的纳米结构。该计划将促进教学，培训和学习的各个层次的学生跨学科的方式。它将进一步涉及代表性不足的群体的参与，加强研究和教育的基础设施，以及工业推广。PI将与附近学区的高中教师合作，促进与材料科学和工程相关的学习和理解。

TECHNICAL SUMMARY:With a program on polymer self-assembly of directed hybrid nanostructures the PI will pursue the synthesis, characterization and structure-property correlation studies for novel classes of nanostructured amorphous, polycrystalline and single crystal materials with expitaxial relations to their substrates. Networked morphologies are targeted as obtained from self-assembly of ABC triblock terpolymers used as structure directing agents for inorganic materials including oxides, metals and semiconductors. The aim of the proposed program is to understand the underlying fundamental chemical, thermodynamic, and kinetic formation principles enabling generalization of results over a wider class of materials systems. The research includes synthesis of all necessary organic/polymer and inorganic components, characterization of assembly structures using various scattering and electron microscopy techniques, study of specific properties, and investigation of optoelectronic devices. Interdisciplinarity will be a central feature of the effort. The project will also involve extensive interactions with several researchers at Cornell and abroad (Cambridge and Oxford Universities, UK) who have complementary expertise.NON-TECHNICAL SUMMARY:The PI proposes to study the fundamental principles for successfully nanostructuring various materials such as oxides, metals, and semiconductors with the help of specially designed polymers. These polymers should enable assembly of highly complex structures. If successful, this program will have significant impact in a broad range of areas from microelectronics to energy conversion and storage enabled by novel ways to organize matter into nanostructures with functionalities not previously available. The program will promote an interdisciplinary way of teaching, training, and learning for students at all levels. It will further involve the participation of underrepresented groups, enhancement of the infrastructure for research and education, and industrial outreach. The PI will work with high school teachers in a nearby school district to promote learning and understanding related to materials science and engineering.
