Study on the role of electron spin in charge transport process using by optical detected electron spin spectroscopy

为了优化瞬时磁光效应的检测单元，组装了一套稳态法拉第旋转角测量系统。在外场作用下对FR信号进行监测，建立了探测光和合适的光桥布置作为检测系统。此外，还研究了有效产生自旋极化物质的合适的光化学体系，并适合于时间分辨测量系统的性能验证。将脉冲激光系统与瞬变磁光探测装置相结合并同步，完成了国产瞬变磁光系统的研制，作为观测瞬变磁光效应的系统。我不断改进自制系统的性能，并对电荷传输过程中的自旋动力学进行研究。

A steady-state faraday rotation (FR) measurement system was assembled for the optimization of the detection units of a transient magneto-optical effect. Monitoring the FR signal under the external field, both probe light and the suitable arrangements of the optical bridge system were established as a detection system. In addition, it has been investigated to find the appropriate photochemical systems which produce the spin polarized species efficiently and are suitable for the performance confirmation of the time-resolved measurement system. Combining and synchronizing the pulsed laser system with FR detection units, the home-build transient FR system has been completed as the system to observe the transient magneto-optic effects. I continue to improve the performance of home-build system and the research on the spin dynamics in the charge transport process.
