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（甚至半金属）材料集成的可能性是该项目的一个突出动机。 该方法是开发预测性的物理模型，为有机电致伸缩器为基础的自旋电子器件，以提供定量评估这些材料的真正潜力的应用。 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：拟议活动的智力价值包括推进对自旋注入和输运的基本理解，以及探索新器件和可能的应用。 最近证明了将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预期的更大功能和性能的新器件创造了令人兴奋的机会。 提出的预测理论模型可能会获得重大的技术影响。 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：该项目将通过研究生在一个令人兴奋的跨学科领域的参与产生广泛的教育影响。 这一领域的研究涉及凝聚态物理学、有机化学和电子学，跨越了许多界限。 此外，拟议的方案由于参与了明尼苏达大学材料研究科学和工程中心及其完善的外联网络，能够从传统上代表性不足的群体中招募妇女和学生，从而扩大了教育范围。

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.
