| dc.description.abstractEn | We show that the huge Seebeck coeffcients observed recently for ionic conductors, arise from aratchet effect where activated jumps between neighbor sites are rectified by a temperature gradient,thus driving mobile ions towards the cold. For complex systems with mobile molecules likewater or polyethylen glycol, there is an even more effcient diffusiophoretic transport mechanism,proportional to the thermally induced concentration gradient of the molecular component. Withoutfree parameters, our model describes experiments on the ionic liquid EMIM-TFSI and hydratedNaPSS, and it qualitatively accounts for polymer electrolyte membranes with Seebeck coeffcientsof hundreds of $k_B/e$. | |
