摘要	We report the electronic transport properties of the MnAs(001)/InP(001) magnetic tunnel junctions by first principles calculations. The half-metallic MnAs was predicted as a result of 100% spin polarization and then minority spin current is absolutely inhibited when the bias voltage is applied to terminals of both MnAs and InP. Majority spin current is inhibited when the bias voltage is less than 0.8 V and "relaxed" when the bias voltage increases. Spin-up and spin-down currents flowing in opposite directions are proved to be induced by temperature difference between left and right electrodes called Seebeck Effect rather than external electrical bias. Thermal current was demonstrated perfect spin filtering effects to indicating possible use for fabrication of highly-efficient spin filter devices in this study. (C) 2015 Elsevier B.V.
