Negative Differential Resistance in the Scanning Tunneling Spectroscopy of Organic Molecules

The conductance-voltage spectrum of molecular nanostructures measured by scanning tunneling spectroscopy (STS) is generally assumed to reflect the local density of states of the molecule. This excludes the possibility of observing negative differential resistance (NDR). We report here the observation of NDR in the scanning tunneling microscope (STM) current-voltage (I-V) characteristics of self...

Scanning tunneling spectroscopy of single DNA molecules.

We briefly present the results of recent experiments of transverse scanning tunneling spectroscopy of homogeneous poly(dG)-poly(dC) DNA molecules and discuss them in the light of theoretical investigation. A semiempirical theoretical model is adopted to describe the transverse tunneling current across a DNA molecule placed between a metallic gold substrate and a metallic STM tip. We show that t...

Scanning tunneling microscopy and spectroscopy investigations of QCA molecules.

Quantum-dot cellular automata (QCA), a computation paradigm based on the Coulomb interactions between neighboring cells. The key idea is to represent binary information, not by the state of a current switch (transistor), but rather by the configuration of charge in a bistable cell. In its molecular realization, the QCA cell can be a single molecule. QCA is ideally suited for molecular implement...

Negative Di erential Resistance in the Scanning TunnelingSpectroscopy of Organic

In the interpretation of scanning tunneling spectroscopy (STS) data on molecular nanostructures the tunneling conductance is often assumed to be proportional to the local density of states of the molecule. This precludes the possibility of observing negative diierential resistance (NDR). We report here the observation of NDR in the current-voltage (I-V) characteristics of a self-assembled monol...

Scanning Tunneling Spectroscopy of C36

The local density of electronic states NsEd has been measured on C36 thin films using scanning tunneling spectroscopy (STS). A 0.8 eV energy gap and sharp features in NsEd with widths as small as 0.2 eV can be ascribed to the discrete molecular energy levels predicted for the C36 molecule, broadened by intermolecular interactions. However, a more complete agreement between the experimental resu...
