In this talk, the experimental results of spin injection and gate control of spin precession is presented. The original Datta-Das prediction of a gate voltage controlled conductance oscillation in a spin injected field effect transistor (Spin-FET), caused by coherent spin precession in a Rashba spin-orbit system, is the cornerstone of semiconductor spintronics research. Our result is the first experimental observation and confirmation of the Datta-Das prediction. We also combine spin Hall and Rashba effects to provide two novel results: a direct demonstration of the ballistic spin Hall effect and a new technique for an all-electric measurement of the Datta–Das conductance oscillation.
