We have studied electron transfer through redox molecules adsorbed on a conductive substra scanning tunneling microscopy (STM) in aqueous solution. By adjusting the substrate potentia Fermi levels of the substrate and tip can be easily shifted relative to the energy levels of the mole Aligning the Fermi levels to an energy level, a nearly tenfold increase in the tunneling current that between the substrate and the STM tip via the molecules, due to resonant tunneling is observed experiment also… CONTINUE READING
