Spin-dependent charge transport in organic semiconductors

摘要

Combining the Su-SchrieU'er-Heeger (SSII) model and the non-equilibrium Green's function (NEGF) formalism, we have theoretically studied controllable conductance switching of the organic spintronics and interpreted it with the voltage-induced polaron picture. The exponential decay of magnetoresistance with bias voltage is qualitatively consistent with the experimental result.
