Conductivities from gold and nickel leads. a The I–V curves of 1,4-benzenedithiol with the gold and nickel leads are compared. b The base-10 log of conductance versus V curves of 1,4-benzenedithiol with the gold and nickel leads are compared. Benzenedithiol with the nickel leads is predicted by the 2-RDM method to have approximately twice the conductance of the molecule with the gold leads, which is consistent with recent experimental observations30
