Sažetak
We present the calculations of the electronic structure and transport properties of the model of oligophenylene-vinilene-n molecules in contact with gold electrodes. The transmission spectra and the current-voltage characteristics were obtained using a newly developed method TranSIESTA which makes a full selfconsistent description of the molecule and the electrodes with different electrochemical potentials. The common feature of the zero bias transmission spectra in all the systems considered (n=3, 4, 5) is a broad resonance just below the Fermi level and a number of narrow resonances above 1 eV of the Fermi level. At finite bias the transmission curves show clear differences in the detailed peak structure, reflecting the strongly perturbed levels. We comment on the observed scaling properties of the spectra and the regime of applicability of the coherent transport model.
