多环烃分子的量子输运：格林函数方法
Quantum transport through polycyclic hydrocarbon molecules: Green's function approach
摘要：
利用格林函数方法研究了多环烃分子在两个金属电极上的量子输运性质。基于紧束缚模型的参数化方法被用来研究电子在分子桥体系中的输运。从分子-电极耦合强度和量子干涉效应两个方面讨论了输运性质。
英文摘要：
Quantum transport properties through single polycyclic hydrocarbon molecules attached to two metallic electrodes are studied by the use of Green's function technique. A parametric approach based on the tight-binding model is introduced to investigate the electronic transport through such molecular bridge systems. The transport properties are discussed in the aspects of (a) molecule-to-electrode coupling strength and (b) quantum interference effect.
