with values reported in Table . We note that our calculated Γ = 2Γ L of 77.2 meV for the BDA-atop-Au junction agrees well with the corresponding value of 85 meV extracted by the Kiguchi group from mechanically-controlled break-junction experiments . The current-voltage characteristics in Fig. mostly reflect the same trends as the conductance values in Tables . Overall, the gold electrodes produces 3 to 5 times greater tunneling current than silver and copper electrodes. The BDT-atop molecular bridge produces the lowest current with Au, Ag, and Cu electrodes. BDT-FCC produces the highest current with Au electrodes whereas BDA-atop produces the highest current with Ag electrodes. Interestingly, BDT-FCC and BDA-atop produce almost the same current with Cu electrodes, leading to superimposed blue and orange lines in Fig. (c). We note that our calculated current of 103 nA at 0.5 V for the BDA-atop-gold junction agrees qualitatively with the corresponding current of 500 nA at 0.5 V measured using mechanically-controlled break junctions by the Kiguchi group 62 .
