【 摘 要 】
We study the role of charge density wave fluctuations on the temperature dependence of Seebeck coefficient in quasi-one-dimensional conductors with a Peierls instability. The description of low-dimensional incommensurate charge density wave fluctuations as obtained by a generalized Ginzburg-Landau approach for arrays of weakly coupled chains is embodied in the numerical solution of the semiclassical Boltzmann transport equation. The energy and temperature dependence of the scattering time of electrons on fluctuations can then be extracted and its influence on the Seebeck coefficient calculated. The connection between theory and experiments carried out on molecular conductors is presented and critically discussed.
