本研究通过理论分析揭示，分子结中库仑相互作用与环境重组效应可相互抵消，从而显著改变塞贝克系数、功率因子及零偏置电导和热电势的定性行为。
AI 中文摘要
我们提出了一项理论研究，聚焦于库仑相互作用对分子结热电性质的影响，假设电子输运受到分子环境中热化声子模式的强烈影响。研究表明，分子态上电子间的库仑相互作用与环境中的重组过程的联合效应，可能显著影响塞贝克系数和功率因子。具体而言，我们证明电子-电子相互作用可以抵消环境分子重组的影响，导致零偏置电导和热电势行为发生定性变化。
英文摘要
We present a theoretical study focused on the influence of Coulomb interactions on thermoelectric properties of molecular junctions assuming that electron transport is strongly affected by thermalized phonon modes in the molecular ambient. It is shown that the combined effect of Coulomb interactions between electrons on the molecular states and the reorganization processes in the ambient may significantly affect both Seebeck coefficient and the power factor. Specifically, we show that electron-electron interactions may counter-balance the effect of the ambient molecules reorganizations resulting in qualitative changes in the behavior of both zero-bias conductance and thermopower.
