Sequence dependent DNA-mediated conduction.
We report on coherent charge transport studies in periodic Poly(dG)-Poly(dC) and aperiodic lambda-phage DNA sequences. The extent and efficiency of charge transfer is discussed as a function of sequence dependent energetics, of temperature dependent base-base couplings, and in relation with experiments.
