Using Fe, Co or Ni chains as electrodes, we designed several annulene-based molecular spintronic devices and investigated the quantum transport properties based on density functional theory and non-equilibrium Green's function method. Our results show that these devices have outstanding spin-filter capabilities and exhibit giant magnetoresistance effect, and that with Ni chains as electrodes, the device has the best transport properties. Furthermore, we investigated the spinpolarized optoelectronic properties of the device with Ni electrodes and found that the spin-polarized photocurrents can be directly generated by irradiating the device with infrared, visible or ultraviolet light. More importantly, if the magnetization directions of the two electrodes are antiparallel, the photocurrents with different spins are spatially separated, appearing at different electrodes. This phenomenon provides a new way to simultaneously generate two spin currents.

Considering the special charge-spin relationships of the carries in organic semiconductors, a simple T-shaped model of organic spin injection device is constructed. Based on the spin-diffusion theory, the current-spin polarization of the T-shaped device is theoretically obtained. It is found that by adjusting the branching current the spin polarization in this T-shaped device is enhanced distinctly compared with precious ferromagnetic/organic semiconductor model. The effects of polaron ratio, electric field and conductivity of the organic semiconductor on current spin polarization of the T-shaped device are also discussed.
