Spin Diffusion in the Finite Magnetic Heterojunction

摘要：

　　Spin diffusion in the finite magnetic heterojunction was explored considering the spin dependent conductivity.In organic semiconductor spintronic devices, the up-spin and down-spin polarons have different density once spin injection happens from ferromagnetic electrodes into organic semiconductors.The difference results in the spin dependent conductivity.The calculations show that the spin injection efficiency is dependent on the spin dependent conductivity and the size of the layers.The spin dependent conductivity has great influence on the spin injection efficiency in the finite magnetic heterojunction, when the spin polarization of the organic semiconductors is moderate.
