Molecular Vibration Spectra by Inelastic Electron Tunneling

Lambe, J., Jaklevic, R. C.·1968·Physical Review

Abstract

An experimental and theoretical study has been carried out on the process of inelastic tunneling between metal films. The experimental results show that this process gives rise to the observation of vibrational spectra for molecules contained in the junction region. The phenomena have been studied for a number of molecular species and at temperatures ranging from 1 to 300\ifmmode^\circ\else\textdegree\fi{}K. The principal effect of temperature is to broaden the observed spectral lines which can be accounted for quantitatively by considering the thermal smearing of the electron distribution in metals. Two detailed interaction mechanisms are discussed which can give rise to infrared dipole or Raman selection rules. None of the experiments carried out thus far can distinguish between these two processes, because of the low symmetry of the molecules used. In addition to the vibrational spectra, it appears that it should be possible to observe electronic transitions as well.

  • Multisite networks may exhibit more complex behaviour due to interplay between constructive and destructive interference effects and environmental noise.

    “While linear networks can already exhibit interesting noise assisted transport phenomena [16, 107-111], multisite networks may exhibit more complex behaviour which arises due to the interplay between a wealth of constructive and destructive interference effects in a quantum dynamical system on the one hand and environmental noise on the other hand [16, 62, 67-70, 77, 112].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
