spin-spin energy

The spin-dependent variable hopping model has been proposed by taking into account the electron-electron Coulomb interaction, the spin-spin exchange interaction and hard gap energy in the same frame, which can well described the observed magnetic transport properties in both Co-ZnO and Fe-ZnO magnetic semiconductor systems.

在Efros变程跃迁导电模型基础上，我们建立了考虑库仑相互作用、载流子之间自旋-自旋交换作用和硬带能的统一模型，成功地解释了ZnO基磁性半导体中观察到的电子输运现象。
