Its academic excellence and advantage both at fundamental and applied level lie in the combination of spin-related phenomena and novel transport properties in molecular or organic materials. However, controlling of organic/inorganic interface, fabrication of an organic/inorganic hybrid system or device, fundamental understanding of new physical behaviors, and exploitation of the possibility of quantum effects in the ultimate molecular-scale limit, are still major challenges in this field. This research is proposed to understand the unique spin-dependent transport mechanisms and development of application device with organic/inorganic hybrid systems. We will address the critical organic/inorganic interface problems and the state-of-the-art fabrication and integration methods for organic spintronic devices, such as organic spin valve and spin transistor. Fundamental issues, such as spin-transport behavior with reduced dimensionality and spin-coupling especially at organic/inorganic interface, should provide not only a better understanding of the mechanism behind these novel properties, but also an excellent starting point for further application in nanodevice. Fabrication of spintronic devices with both bottom-up (self-assembly) and top-down (e-beam lithography) techniques, probing spin coupling at organic/inorganic interface with spin-polarized scanning tunneling microscopy, and exploitation of the interplay between fundamental physical length and the sample size of nanometer scale should be the major subjects in this proposal. Besides, the theoretical study also plays an important role in this project. In particular, the interplay between the critical physical length and dimensionality or size confinement effect as well as the behavior of the dynamic response will be intensively studied with theory, not only for interpretation of the experimental results, but also to trigger new design or guideline on further experiment. Finally, besides the scientific significance mentioned above, the future outcome of the project should also benefit the key technology in the related industrial applications with organic/inorganic hybridsystems, such as nanoelectronics, organic electronics, and organic spintronics as well.有機自旋電子學奈米磁學自旋依賴傳輸自旋電子掃描穿隧顯微鏡有機電子學奈米電子學自旋閥元件有機/無機介面電子束蝕刻自組裝organic spintronicsnanomagnetismspin-dependent transportSP-STMspin-valve devicee-beam lithographyself-assembly
