基于静态极化子Su-Schrieffer-Heeger模型和非平衡绿色函数理论，研究了低温下有机自旋阀系统的负微分电阻（NDR）效应，并从自掺杂的角度对其进行了解释.理论上预测，由于负磁电阻效应的存在，将产生超过300%的巨负磁电阻效应。
Based on the static polaron Su–Schrieffer–Heeger model and the nonequilibrium Green's function formalism, we investigate the negative differential resistance (NDR) effect in organic spin-valve systems at low temperature and interpret it with a self-doping picture. A giant negative magnetoresistance exceeding 300% is theoretically predicted as the results of the NDR effects.
