Abstract EN
We report experimental measurements of molecular conductance as a single molecular sensor by using scanning tunneling microscope-based break-junction (STM-BJ) technique.
The gap was created after Au atomic point contact was ruptured, and the target molecule was inserted and bonded to the top and bottom electrodes.
We successfully measured the conductance for a series of amine-terminated oligophenyl molecules by forming the molecular junctions with Au electrodes.
The measured conductance decays exponentially with molecular backbone length, enabling us to detect the type of molecules as a molecular sensor.
Furthermore, we demonstrated reversible binary switching in a molecular junction by mechanical control of the gap between the electrodes.
Since our method allows us to measure the conductance of a single molecule in ambient conditions, it should open up various practical molecular sensing applications.
