Materials World Network Collaboration: Spin-and Time-Resolved Studies of Organic Spintronics Interfaces

该项目是德国凯泽斯滕大学（UKL）和罗切斯特大学（UOR）之间的合作研究成果。实验计划的目的是解决有关自旋弛豫，自旋相关的运输，自旋注入，和磁性现象在与有机半导体（OSC）的接口的基本问题。 重点主要是在无机固体和有机材料之间的界面上的自旋注入。 在这些研究中，将使用自旋和时间分辨光电子能谱、时间分辨磁光克尔效应、光电子能谱和逆光电子能谱以及原子力显微镜和磁力显微镜进行测量。这两个团队（UOR和UKL）都有独特的设施互补，但都是这个项目的成功很重要。 UKL团队在自旋动力学研究方面得到了广泛认可，是开发自旋和时间分辨光电子能谱的先驱。 UOR团队在有机半导体界面方面拥有十多年的经验。 两个团队之间的密切合作至关重要。该合作还为学生和博士后提供了获得国际研究经验的机会。 拟议的研究介绍了创新的方法来解决有机自旋电子学的未来发展的重要的基本问题。该奖项由国际科学与工程办公室共同资助。

This project is a collaborative research effort between the University of Kaiserslautern (UKL), Kaiserslautern, Germany and the University of Rochester (UOR). The objective of the experimental program is to resolve fundamental questions regarding spin relaxation, spin-dependent transport, spin injection, and magnetic phenomena at interfaces with organic semiconductors (OSC). The focus is mainly on spin injection across the interface between an inorganic solid and organic materials. For these studies, measurements will be carried out using spin- and time-resolved photoemission spectroscopy, time-resolved magneto-optical Kerr effect, photoemission and inverse photoemission spectroscopy, and atomic force microscopy and magnetic force microscopy. Both teams (UOR and UKL) have unique facilities complementary to each other but all are important for the success of this project. The UKL team is well recognized in the study in spin dynamics and is the pioneer to develop spin- and time-resolved photoemission spectroscopy. The UOR team has more than a decade of experience in interfaces in organic semiconductors. A strong collaboration between both teams is essential. The collaboration also offers students and postdoctoral associates the opportunity to gain an international research experience. The proposed study introduces innovative approaches to address fundamental issues important for the future development of organic spintronics. This award is co-funded by the Office of International Science and Engineering.
