For more integration of semiconductor devices, a study for development of the beyond-CMOS technology was carried out from the viewpoint of spintronics. In this study, the achievement of room-temperature-spin-transport in the p-type Si, p-type Ge and n-type Ge with spin injection by using the spin-pumping and with spin detection by using the inverse spin-Hall effect in the non-magnetic metal attached to the target materials was focused.In this study, the spin-pumping-induced spin transport in the p-Si at room temperature was demonstrated. Also, spin injection into the p-Ge was achieved. These results were suggested that the evaluation method of the spin transport in this study was able to be applied to almost all solid-state materials, and the room temperature spin transport in aluminum or graphene was successfully demonstrated as good examples with this method.

为了进一步提高半导体器件的集成度，从自旋电子学的角度对超CMOS工艺的发展进行了研究。本论文主要研究了在p型Si、p型Ge和n型Ge中实现室温自旋输运，利用自旋泵浦实现自旋注入，利用自旋霍尔效应实现自旋探测，并在p-Si中实现了室温自旋泵浦诱导的自旋输运。此外，自旋注入到p-Ge实现。这些结果表明，本研究中的自旋输运的评估方法能够适用于几乎所有的固态材料，并且铝或石墨烯中的室温自旋输运被成功地证明是使用该方法的好例子。
