Silicon (Si) is a promising candidate for spintronics and the information and recently a successful room temperature operation of the spin metal-oxide semiconductor field-effect transistor (MOSFET) in Si has been demonstrated in our group. In addition, the magnitude of spin signal can be enhanced using spin drift effect. However, spin transport under a high electric field has not been fully investigated, which can provide a significant material to discuss bias voltage dependence of the Si spin devices. In this study, we investigated the electric field dependence of spin drift velocity in non-degenerated Si lateral spin valves (LSVs).
