Research Abstract

"Silicon spintronics "is promising for improving functionalities of silicon CMOS technology without scaling. To develop this technology, methods of spin-injection/detection/manipulation for a Si channel must be established. Therefore, in this study, formation technologies of high-quality half-metal full-Heusler alloys, which can become high-efficient spin-injector/detector, on Si were developed. Furthermore, device structures which were suitable for observing behavior of spins were designed.
