| 英文摘要 | We consider spin polarized transport in a ferromagnet-insulator/semiconductor/insulator-ferromagnet junction. We find that the spin current is strongly dependent on the spin configurations, the doping, and space charge distribution in the semiconductor. When the ferromagnet-semiconductor interface resistance is comparable to the semiconductor resistance, the magnetoresistance ratio of this junction can be greatly enhanced under appropriate doping when the space charge effect in the nonequilibrium transport processes is taken into consideration. |
