Simultaneous measurements of tunneling current and displacement current spectroscopy are demonstrated in nanomechanical double-barrier tunneling structures which consist of scanning vibrating probe/vacuum/colloidal Au dots/self-assembled monolayer (SAM)/Au substrate. The displacement current staircase due to Coulomb blockade is observed together with the tunneling current staircase in the nanomechanical double-barrier tunneling structures. In the case of tunneling current spectroscopy, negative differential resistances (NDRs) are also observed. NDRs are concerned with the change in the number of electrons on the Au dot and the tunneling resistance.
