Spin Properties of Transition-Metallorganic Self-Assembled Molecules
This report summarizes SRI's accomplishments on the project, 'Spin Properties of Transition-Metallorganic Self-Assembled Molecules' funded by the Office of Basic Energy Sciences, US Department of Energy. We have successfully carried out all tasks identified in our proposal and gained significant knowledge and understanding of spin-polarized electronic structure, spin relaxation, and spin-dependent transport in transition-metallorganic molecules and enhohedral fullerenes. These molecules contain integrated spin and charge components and will enable us to achieve sophisticated functions in spintronics and quantum computing at molecular level with simple circuitry and easy fabrication. We have developed microscopic theories that describe the underlying mechanisms of spin-dependent porcesses and constructed quantitative modeling tools that compute several important spin properties. These results represent the basic principles governing the spin-dependent behaviors in nanostructures containing such molecules. Based on these results we have shown that novel device functions, such as electrically controlled g-factor and noninvasive electrical detection of spin dynamics, can be achieved in these nanostructures. Some of our results have been published in peer-reviewed journals and presented at professional conferences. In addition, we have established a close collaboration with experimentalists at Oxford University, UK (Dr. J. Morton and Prof. G. Briggs), Princeton University (Dr. A. Tyryshkin and Prof. S. Lyon), University of Delaware (Prof. E. Nowak), and University of California (Profs. R. Kawakami and J. Shi), who have been studying related systems and supplying us with new experimental data. We have provided our understanding and physical insights to the experimentalists and helped analyze their experimental measurements. The collaboration with experimentalists has also broadened our research scope and helped us focus on the most relevant issues concerning these materials.
