英文摘要	In this communication, we demonstrate an approach for conductance measurement of single molecular junctions with different metallic electrodes based on STM-break junction (STM-BJ) technique with electrochemical strategy. Conductance of molecular junctions formed with succinic acid using Cu, Ag and Au as metal electrodes has been systemically studied, the values being 18.6, 13.2 and 5.6 nS for Cu, Ag and Au electrodes, respectively. The observed decrease in conductance indicates the weakening of electronic coupling efficiency at the electrode-molecule contacts in the order of Cu>Ag>Au, which should be taken into account in evaluating the molecular conductance in the junctions.
