      abstract     = {Transition metal complexes are electrofunctional molecules
                      due to their high conductivity and their intrinsic switching
                      ability involving a metal-to-ligand charge transfer. Here, a
                      method is presented to contact reliably a few to single
                      redox-active Ru-terpyridine complexes in a CMOS compatible
                      nanodevice and preserve their electrical functionality.
                      Using hybrid materials from 14 nm gold nanoparticles (AuNP)
                      and
                      bis-{4′-[4-(mercaptophenyl)-2,2′:6′,2″-terpyridine]}-ruthenium(II)
                      complexes a device size of 302 nm2 inclusive nanoelectrodes
                      is achieved. Moreover, this method bears the opportunity for
                      further downscaling. The Ru-complex AuNP devices show
                      symmetric and asymmetric current versus voltage curves with
                      a hysteretic characteristic in two well separated
                      conductance ranges. By theoretical approximations based on
                      the single-channel Landauer model, the charge transport
                      through the formed double-barrier tunnel junction is
                      thoroughly analyzed and its sensibility to the
                      molecule/metal contact is revealed. It can be verified that
                      tunneling transport through the HOMO is the main transport
                      mechanism while decoherent hopping transport is present to a
                      minor extent.},
