铁电体和铁磁体中的电偶极和磁偶极在高温下的自发有序性是非常有趣和有用的。在自旋电子学中，以自旋电流形式的磁性输运被大力研究，但铁电有序的极化电流却没有引起注意。因此，我们提出了一个含时扩散理论的热和极化输运的平面铁电电容器的参数来自一维声子模型。我们预测稳态塞贝克和瞬态珀尔帖效应，等待实验发现。
The spontaneous order of electric and magnetic dipoles in ferroelectrics and ferromagnets even at high temperatures is both fascinating and useful. Transport of magnetism in the form of spin currents is vigorously studied in spintronics, but the polarization current of the ferroelectric order has escaped attention. We therefore present a time-dependent diffusion theory for heat and polarization transport in a planar ferroelectric capacitor with parameters derived from a one-dimensional phonon model. We predict steady-state Seebeck and transient Peltier effects that await experimental discovery.
