摘要

We report on a theoretical study pointing out the fundamental role of the backbone energetics in the charge transfer efficiency of polyG-polyC and polyA-polyT chains. The double-strand DNA (ds-DNA) molecules are modelled in terms of a single channel effective Hamiltonian. By introducing a two-step renormalization scheme analytical results for the energy spectrum and transmission coefficient are derived, and current-voltage characteristics are numerically investigated. Significant modulations of the main I-V features (voltage threshold, current amplitude) are reported and their physical origin is traced back to backbone-induced electronic effects. These results open new perspectives for experimental work aimed at controlling the charge transfer efficiency in nanodevices based on synthetic DNA.
