Effect of disturbance on spin polarized transport through an organic ferromagnetic device
扰动对有机磁体器件自旋极化输运特性的影响

Based on the tight-binding model and the Green's function method,the effects of atomic disorder of lattice configuration and the orientation disorder of side radical spins on the spin polarized transport through a metal/organic-ferromagnet/metal structure are investigated.The results show that the atomic disorder reduces the threshold voltage of the device and suppresses the conducting current.The staircase structure of the current-voltage curve for a molecular device is eliminated when the disorder is enha...
