| 中文摘要 | we have theoretically investigated ballistic electron transport through a combination of magnetic-electric barrier based on a vertical ferromagnet/two-dimensional electron gas/ferromagnet sandwich structure, which can be experimentally realized by depositing asymmetric metallic magnetic stripes both on top and bottom of modulation-doped semiconductor heterostructures. our numerical results have confirmed the existence of finite spin polarization even though only antisymmetric stray field b-z is considered. by switching the relative magnetization of ferromagnetic layers, the device in discussion shows evident magnetoconductance. in particular, both spin polarization and magnetoconductance can be efficiently enhanced by proper electrostatic barrier up to the optimal value relying on the specific magnetic-electric modulation.
