Inelastic Electron Tunneling Spectroscopy

Science, 1983
Inelastic electron tunneling spectroscopy is a useful technique for the study of vibrational modes of molecules adsorbed on the surface of oxide layers in a metal-insulator-metal tunnel junction. The technique involves studying the effects of adsorbed molecules on the tunneling spectrum of such junctions.

Inelastic electron tunneling spectroscopy

TrAC Trends in Analytical Chemistry, 1982
Abstract Inelastic electron tunneling spectroscopy (IETS) is a relatively new form of vibrational spectroscopy which is able to address problems previously unsolved by either IR or Raman. It is particularly useful for surface analysis.

Inelastic electron tunnelling spectroscopy

Journal of Physics C: Solid State Physics, 1983
Experiments have used inelastic electron tunnelling spectroscopy as a method of measuring the phonon density of states of the tunnelling barrier. The magnitude of the measured d2I/dV2 characteristic is proportional to the density of phonon states multiplied by a weighting factor, which depends on the strength of the interaction between the electron and

Inelastic electron tunnelling spectroscopy

Journal of Physics C: Solid State Physics, 1985
The authors describe the physical basis and experimental techniques of inelastic electron tunnelling spectroscopy. A discussion of the essential features of quantitative theory shows how to set about detailed analysis of spectra. The power and versatility of the technique are illustrated by accounts of a variety of applications, and suggestions are ...

Spectroscopy of Biological Compounds with Inelastic Electron Tunneling

Science, 1974
Metal-insulator-metal electron tunnel junctions can be doped with a solution of an organic compound by placing a drop of the solution on the insulator and spinning off the excess. Electrical measurement of the second derivative of voltage with respect to current, as a function of applied voltage, then gives a spectrum of vibrational modes equivalent to

Electronic transitions observed by inelastic electron tunneling spectroscopy

Solid State Communications, 1972
We wish to discuss the application of IETS to the observation of electronic, rather than vibrational transitions. This extension of the method seemed interesting for several reasons.

Inelastic Electron Tunnelling Spectroscopy

1980
Inelastic electron tunnelling spectroscopy (IETS) is fast becoming established as a useful technique for the study of vibrational modes of surface adsorbates. It owes its existence to some observations in the middle 1960’s at the Ford Motor Company Laboratories by R. C. JAKLEVIC and J. LAMBE [1, 2].

Inelastic Electron Tunneling Spectroscopy and Vibrational Coupling

The Journal of Physical Chemistry A, 2006
We discuss the relationship between the inelastic electron tunneling spectroscopy (IETS) and vibronic coupling constant within the Green's function formalism at a level of perturbation theory approximation. We also compare our results with experimental measurements. Our results can provide insights into the mechanism of active vibronic modes for IETS.

Inelastic electron tunneling spectroscopy

2007
Inelastic Electron Tunneling Spectroscopy (IETS) is a method to measure vibronic and electronic excitation of molecules deposited as interlayers in tunnel junctions. In this article the method itself is briefly, discussed and compared with other techniques of, surface vibrational spectroscopy.
