Abstract

The thermoelectric opportunities of some highly conducting quasi-one dimensional (Q1D) organic crystals are studied theoretically. The electrical conductivity, Seebeck coefficient and electronic thermal conductivity are investigated as functions of crystal parameters. Obtained dependences are used to determine the optimal expected values of ZT at room temperature. The mechanism for ZT enhancement and the needed tuning of crystal parameters in order to maximize the enhancement are analyzed in detail. It is shown that due to the interference of two main electron-phonon interaction mechanisms, values as high as ZT ∼ 20 are possible both in nand p-type Q1D materials. Recommendations are elaborated for the realization of such materials.
