Polymer self-assembly directed hybrid nanostructures: from amorphous to polycrystalline to single crystal materials

技术概述：PI将利用定向杂化纳米结构的聚合物自组装计划，对与其衬底具有外延关系的新型纳米结构非晶、多晶和单晶材料进行合成、表征和结构-性能相关性研究。网络形态的目标是通过自组装ABC三嵌段三元聚合物作为无机材料的结构导向剂，包括氧化物、金属和半导体。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，从而能够在更广泛的材料系统中推广结果。研究包括合成所有必要的有机/聚合物和无机成分，使用各种散射和电子显微镜技术表征组装结构，研究特定性质，以及研究光电子器件。跨学科性将是这一努力的一个核心特征。该项目还将与康奈尔大学和国外(英国剑桥大学和牛津大学)的几名研究人员进行广泛的互动，他们拥有互补的专业知识。非技术概述：PI建议在特殊设计的聚合物的帮助下，研究成功实现氧化物、金属和半导体等各种材料纳米结构的基本原理。这些聚合物应该能够组装高度复杂的结构。如果成功，这项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，这是通过将物质组织成纳米结构的新方法实现的，这些纳米结构具有以前没有的功能。该计划将为各级学生推广一种跨学科的教学、培训和学习方式。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.
