ABSTRACT:
A spin transistor having wide ON/OFF operation margin and producing less noise is provided. The spin transistor includes a substrate having a channel, a source, a drain and a gate formed on the substrate. The source and the drain are formed to have magnetization directions perpendicular to the length direction of the channel. The ON/OFF operations of the spin transistor can be controlled by generating a spin-orbit coupling induced magnetic field to have a direction parallel or anti-parallel to the magnetization directions of the source and the drain.
