During the pursuit of longer spin information preservation and flexibility of devices, organic molecules show their advantages in spintronics. By choosing appropriate organic and inorganic materials, fabrications of systems containing these important functions can be achieved. In this project, we propose to use spin-polarized scanning tunneling microscopy (SP-STM) and spectroscopy (SP-STS) to resolve local spin information below nanoscale in metal-organic systems. Interfacial interactions between molecules and metals, which are vital for electronic and magnetic states of the systems, can be directly imaged and analyzed with SP-STM. Our successful preparations of molecules on metal substrates and metal-organic coordination provide two prototypes for investigations. Through our research on different systems, a more comprehensive understanding of metal-organic interfaces can be established in the end and assists spintronics to step further.自旋電子學自旋極化掃描穿隧顯微鏡有機分子表面界面薄膜交換耦合spintronicsspin-polarized scanning tunneling microscopyorganic moleculessurfaceinterfacefilmsexchange coupling藉自旋極化掃描穿隧顯微鏡對奈米尺度金屬-有機界面磁性行為之研究(33)
