非中心对称电子-声子耦合系统中的Seebeck棘轮理论
Theory of Seebeck ratchet in noncentrosymmetric electron-phonon coupled system
摘要：
提出了非中心对称电子-声子耦合系统的热电效应，即电子和声子之间的温度差而不是空间温度梯度引起电流。这是固体中Seebeck棘轮的一种实现，电子的能量色散不对称，动力学声子作为标量势的涨落并感应出直流电流。本文还讨论了该机制的可能实现。
英文摘要：
A thermoelectric effect of the noncentrosymmetric electron-phonon coupled system is proposed, in which a temperature difference between electrons and phonons, instead of a spatial temperature gradient, induces an electric current. This is a realization of Seebeck ratchet in solids with the asymmetric energy dispersion of electrons, and the dynamical phonons act as the fluctuation of the scalar potential and induce the dc current. Possible realizations of this mechanism are also discussed.
