Abstract

We describe an electron filter that exploits the known transmission properties of quantum point contacts to allow local and tunable control of the spin polarization in a semiconductor. When properly configured, the conductance of this device gives a direct measure of the spin polarization of the carriers transmitted through it. These predictions are confirmed by numerical simulations, performed for a spin filter with realistic device parameters.
