The electronic transport properties of two types of benzothiophene-based molecular wires (linear and helical molecular wires) were studied via theoretical calculations. In the molecular bridge system where these molecules are connected to the gold electrodes by S-Au bonds, the transmission peaks were found to lie at energies somewhat lower than 0.5 eV below the Fermi level for both cases. Upon iodine doping, the threshold bias voltage was reduced.
