项目摘要

The objective of this research is to use light scattering and other optical techniques on organic polymers/molecules in order to decipher the local microstructure, which impact device performance, and to investigate surface-charge accumulation and charge transport in metal-organic interfaces using electric field-induced Raman scattering. The approach is (1) to grow thin films of organic polymers/molecules and nanoparticles for photophysical studies; (2) fabricate organic light-emitting diodes and organic spin-valve structures mainly as subjects for spectroscopic studies; (3) fabricate ordered organic light-emitting diode nanostructures. Vibrational spectroscopy from oriented films and nanofibers of organic materials in working light-emitting diode structures will probe structure-property relationships and their influence on both charge-transport and optical properties, and reveal the nature of polarons and bipolarons.The broader impact of the proposed work has several facets. The proposed project aims at establishing a collaboration between the Physics and Electrical Engineering departments at the University of Missouri-Columbia, in the field of organic optoelectronics. The overall goal is to strengthen the undergraduate and graduate Physics and Engineering programs by emphasizing the natural connection between the processes of learning and discovery. The two new proposed laboratory-based courses will provide more hands-on experience to graduate/undergraduate students relevant for 21st century science and technology, which will prepare them for employment in materials science and organic/inorganic semiconductor-based academic research or industry. The University of Missouri is committed to the recruitment and retention of minority students; both the PIs are women and thus excellent role models and mentors for female students in science and engineering.
本研究的目的是利用光散射和其他光学技术对有机聚合物/分子进行研究,以解读影响器件性能的局部微观结构,并利用电场诱导拉曼散射研究金属-有机界面中的表面电荷积累和电荷输运。该方法是:(1)生长用于光物理研究的有机聚合物/分子和纳米颗粒薄膜;(2)制作有机发光二极管和有机自旋阀结构,主要用于光谱学研究;(3)制备有序有机发光二极管纳米结构。利用发光二极管结构中有机材料的定向薄膜和纳米纤维的振动光谱学研究结构-性质关系及其对电荷输运和光学性质的影响,揭示极化子和双极化子的性质。拟议工作的更广泛影响有几个方面。拟议的项目旨在建立密苏里-哥伦比亚大学物理系和电气工程系在有机光电子学领域的合作。总体目标是通过强调学习和发现过程之间的自然联系来加强本科和研究生物理和工程课程。这两门以实验室为基础的新课程将为研究生/本科生提供更多与21世纪科学和技术相关的实践经验,为他们在材料科学和有机/无机半导体为基础的学术研究或行业就业做好准备。密苏里大学致力于招收和留住少数族裔学生;两位pi都是女性,因此是理工科女学生的优秀榜样和导师。
