Conductance Modulation in an α-Terthiophene Molecular Junction Characterized by Surface-Enhanced Raman Scattering
نویسندگان
چکیده
We fabricate α-terthiophene single-molecule junctions (SMJs) and characterize their conductive states by the simultaneous measurements of surface-enhanced Raman scattering (SERS) electronic conductance. The SMJ showed broad conductance distribution due to different portions multiple aromatic rings connected electrodes. SERS spectra obtained measurement vibrational energy C−C stretching mode depends on calculated density-functional theory (DFT) explain tendency shift for typical junction structures. Therefore, DFT calculation have revealed that modulation originates from change in connecting point SMJ. These findings provide efficient information building molecule-based circuits lead potentiometry with rings.

Surface-Enhanced Raman Scattering in Molecular Junctions
Surface-enhanced Raman scattering (SERS) is a surface-sensitive vibrational spectroscopy that allows Raman spectroscopy on a single molecular scale. Here, we present a review of SERS from molecular junctions, in which a single molecule or molecules are made to have contact from the top to the bottom of metal surfaces. The molecular junctions are nice platforms for SERS as well as transport meas...
متن کاملSurface-enhanced Raman scattering
We present an introduction to surface-enhanced Raman scattering (SERS) which reviews the basic experimental facts and the essential features of the mechanisms which have been proposed to account for the observations. We then review very recent fundamental developments which include: SERS from single particles and single molecules; SERS from fractal clusters and surfaces; and new insights into t...

During that process, photons may lose energy to, or gain it from, vibrational excitations. A change in the photon energy must produce a concomitant shift in the frequency of the scattered light (see box 1). The phenomenon, called the Raman ...

On the basis of different types of experiments, we develop implicitly the model of surfaceenhanced Raman scattering (SERS) of adsorbates on metal s u r f a c g . The long-range enhancement by resonances of the macroscopic laser and Stokes field is separated quantitatively from the metal eledmn-mediated resonance Raman effect. The latter mechanism proceeds b y increased electron-photon coupling ...
متن کاملEnhanced Raman Scattering by Molecular Nanoaggregates
The formation of a molecular aggregate in a confined, nanodimensioned region of space leads to what might be termed a ‘molecular nanoaggregate’. The present review deals with a theoretical formulation termed ‘aggregation-enhanced Raman scattering’ (AERS), and its use in discussion of relative Raman band intensities and selection rules for nanoaggregates. AERs represents a concept for discussion...
