这份职业建议书侧重于基于自旋注入和磁性有机发光二极管(OLED)自旋-轨道耦合修饰的有机自旋电子学发展的研究和教育。这个职业项目的目标是开发一种新的方法来控制有机半导体器件中的激发态过程和电荷输运。智能优势：这项综合研究将解决两个关键挑战：自旋极化电荷注入和利用纳米点铁磁电极和可溶性有机材料混合来修饰磁性OLED中的自旋-轨道耦合。自旋极化的电荷注入和自旋-轨道耦合的修饰将被用来控制依赖于磁场的电荷输运和依赖于自旋的激子动力学过程。这些研究将集中在三个关键的基本问题上：纳米级铁磁/有机异质结的自旋输运，依赖于自旋轨道耦合的磁电阻，以及基于磁性有机OLED的自旋注入产生的激子之间的合作相互作用，以开发有机自旋电子学。广泛的影响：拟议的职业项目对研究和教育有两个更广泛的影响。研究成果包括利用纳米点铁磁电极的自旋注入控制激发态过程和电荷输运的新方法的发展，以及有机材料混合引起的自旋-轨道耦合的修正。提出的研究将增加对有机半导体器件中自旋输运和自旋相关激子过程的关键理解。这一新认识将在很大程度上促进磁性有机发光、磁性激光和磁性光伏器件在国防和能源技术应用中的发展。教育影响包括课程开发、学生指导、少数族裔和女性参与，以及通过利用PI的经验以及与田纳西大学现有的工程学院多样性和外联计划的具体项目互动，在专注于磁性有机半导体器件的工程学科教育中向高中生开展外联活动。

This career proposal focuses on the research and education in the development of organic spintronics based on spin injection and modification of spin-orbital coupling in magnetic organic light-emitting diodes (OLEDs). The goal of this career project is to develop a novel approach to control the excited state processes and charge transport in organic semiconductor devices by using magnetic field. Intellectual Merit: The integrated research will address two critical challenges: spin-polarized charge injection and modification of spin-orbital coupling in magnetic OLEDs by using nano-dot ferromagnetic electrodes and soluble organic materials mixing. Spin-polarized charge injection and modification of spin-orbital coupling will be used to control magnetic field-dependent charge transport and spin-dependent exciton dynamic processes. The investigations will focus on three critically important fundamental issues: spin transport across nanoscale ferromagnetic/organic heterojunction, spin-orbital-coupling dependent magnetoresistance, and cooperative interaction of spin injection-generated excitons based on magnetic organic OLEDs for the development of organic spintronics.Broader Impact: The proposed career project has two broader impacts on research and education. The research impact includes the development of new approach to control excited state processes and charge transport by using both spin injection from nano-dot ferromagnetic electrodes and modification of spin-orbital coupling from organic materials mixing. The proposed studies will increase the critical understanding of spin transport and spin-dependent excitonic processes in organic semiconductor devices. The new understanding will largely contribute to the development of magnetic organic light-emitting, magnetic lasing, and magnetic photovoltaic devices in the applications of national defense and energy technologies. The educational impact includes the curriculum development, student mentoring, minority and women involvement, and outreach activities to high school students in the education of engineering disciplines with concentration in magnetic organic semiconductor devices through using the PI's experience and project-specific interaction with existing College of Engineering diversity and outreach programs at the University of Tennessee.
