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.

铁电电容器的传输理论

即使在高温下，铁电体和铁磁体中电偶极子和磁偶极子的自发次序也很引人入胜且有用。自旋电子学已对自旋电流形式的磁性传输进行了深入研究，但铁电有序极化电流却引起了人们的注意。因此，我们提出了一种时变扩散理论，用于平面铁电电容器中的热和极化传输，其参数来源于一维声子模型。我们预测等待实验发现的稳态塞贝克效应和瞬态珀尔帖效应。
