Organic Semiconductor Spin Injection and Spin Transport

有机半导体自旋注入和自旋输运本研究的目的是探索由共轭有机半导体制成的自旋电子器件。将有机半导体与强铁磁性（甚至半金属）材料集成的可能性是该项目的显著动机。该方法是为基于有机半导体的自旋电子器件开发预测物理模型，以便对这些材料在该应用中的真正潜力进行定量评估。明尼苏达大学PI将与洛斯阿拉莫斯国家实验室的研究人员密切合作。智力价值：所提议的活动的智力价值包括对自旋注入和输运的基本理解的进步，以及对新设备和可想象的应用的探索。最近证明了有机材料与磁性材料集成的可行性，以及有机半导体的某些固有特性，为探索具有比传统未来电子技术更大功能和性能的新设备创造了令人兴奋的机会。提出的预测理论模型可能会产生重大的技术影响。然而，这项工作显然是探索性的，并追求长期目标。更广泛的影响：通过研究生在一个令人兴奋的跨学科领域的参与，该项目将产生广泛的教育影响。这个领域的研究跨越了许多边界，涉及凝聚态物理、有机化学和电子学。此外，由于PI参与了明尼苏达大学材料研究科学与工程中心及其完善的外展网络，该计划通过其招募女性和传统上代表性不足的群体的学生的能力，获得了额外的教育范围。

Organic Semiconductor Spin Injection and Spin TransportThe objective of this research is to explore spintronic devices made from conjugated organic semiconductors. The possibility to integrate organic semiconductors with strongly ferromagnetic (even half-metallic) materials is a salient motivation for this project. The approach is to develop predictive physical models for organic semiconductor-based spintronic devices in order to provide a quantitative assessment of the true potential of these materials for that application. The University of Minnesota PI will work closely with researchers at Los Alamos National Laboratory.Intellectual Merit:The intellectual merit of the proposed activity includes the advancement of the fundamental understanding of spin injection and transport, and the exploration of new devices and conceivable applications. A recently demonstrated feasibility to integrate organic materials with magnetic materials, together with certain intrinsic properties of organic semiconductors, create exciting opportunities to explore new devices with much greater functionality and performance than expected from conventional future electronics technology. The proposed predictive theoretical models are likely to acquire significant technological impact. However, the work is clearly exploratory and pursues long-term objectives. Broader Impact:The project will have broad educational impact through the involvement of graduate students in an exciting interdisciplinary field. Research in this area crosses many boundaries by involving condensed matter physics, organic chemistry, and electronics. Furthermore, the proposed program attains additional educational scope through its ability to recruit women and students from traditionally under-represented groups due to the PI's participation in the University of Minnesota Materials Research Science and Engineering Center and its well-developed outreach network.
