局域基团对单个共轭分子电子输运的影响

Effect of localizing groups on electron transport through single conjugated molecules

Santanu K. Maiti

摘要:

本文用格林函数方法研究了夹在两个非超导电极之间的单个共轭分子的电子输运性质。基于紧束缚模型,我们进行了参数计算,以表征电子输运通过这样的分子桥。电子输运性质受(a)这些共轭分子中局域基团的存在和(b)分子与电极的耦合强度的显著影响,并且,在这里,我们的结果集中在这两个方面。

英文摘要:

Electron transport properties through single conjugated molecules sandwiched between two non-superconducting electrodes are studied by the use of Green's function technique. Based on the tight-binding model, we do parametric calculations to characterize the electron transport through such molecular bridges. The electron transport properties are significantly influenced by (a) the existence of localizing groups in these conjugated molecules and (b) the molecule to electrode coupling strength, and, here we focus our results in these two aspects.
