Transport properties through an aromatic molecular wire

Abstract:

The quantum transport properties through a finite homogeneous chain of aromatic molecules composed by benzene rings connected to two semi-infinite leads are investigated. The study is based on the tight-binding approach using semi-analytic methods of Green's function techniques within a real space renormalization scheme. The transmission probability and the characteristic diagram I−V of an aromatic molecular wire are calculated as a function of the molecule-leads coupling and the intra-rings coupling parameters. The obtained results show a good agreement with the previous reported DFT calculations.
