Abstract
We propose a scheme to realize electron-spin filtering based on generic ferromagnetic and semiconductor hybrid nanosystem, which can be experimentally realized by depositing a magnetized ferromagnetic stripe with arbitrary magnetization direction on the surface of a semiconductor heterostructure. It is shown that large spin-polarized current can be achieved in the device, which may provide an alternative scheme to spin-polarize electrons into semiconductors and such a device may be used as an electron-spin filter.
