Abstract: We propose a spin field effect transistor driven by spin biases which are externally generated in the source and drain electrodes. We employed the Keldysh non-equilibrium Green's function formalism to evaluate the charge and spin currents through the transistor, and verify the operation of the transistor as predicted by a semiclassical model. Our calculations show that in the off state, both the charge and spin currents are suppressed. In the on state, the device allows only the spin current to pass through but not charge current, thus potentially improving the energy efficiency of the device. © 2012 American Institute of Physics.
