Inelastic electron tunnelling spectroscopy in glasses

Physica B+C, 1984
The technique of inelastic electron tunnelling spectroscopy can be used to study the virational density of states g(ω) ofamorphous materials by using them as the barrier. With appropriate preparation techniques it has proved possible to measure inelastic tunnelling spectra in a range of insulators, including SiO x , GeO x , B 2 O 3 and MnF 2 .

Inelastic Electron Tunneling Spectroscopy

1987
Inelastic electron tunneling spectroscopy,(1,2) also known as IETS or tunneling spectroscopy, is a sensitive technique for measuring the vibrational spectra of molecules. At present, it is particularly well suited to measuring the vibrational spectra of a monolayer or submonolayer of molecules adsorbed on aluminum or magnesium oxide or on metal ...

Inelastic electron tunneling spectroscopy of Sn oxide tunnel barriers

Vacuum, 1995
We have measured tunnel spectra of Sn/Sn oxide/Pb tunnel junctions. Sn oxide phonon spectra are largely affected by humidity conditions. Certain anomalous behaviours are observed in wet-prepared Sn/Sn oxide/Pb tunnel junctions. The intensity of vibrational modes of molecules adsorbed on the Sn oxide is observed to be much weaker than that of molecules ...

Inelastic electron tunneling: an alternative molecular spectroscopy

The Journal of Physical Chemistry, 1993
The basic theoretical and experimental concepts required for an understanding of inelastic electron tunneling spectroscopy (IETS) are presented. While most of the applications of IETS to date have centered on surface chemical analysis, the thrust of the present review is to present IETS as an alternative molecular spectroscopy.

Surface Phonons and Inelastic Electron Tunnelling Spectroscopy of GaSe

Europhysics Letters (EPL), 1987
We compare inelastic electron tunnelling measurements by Yamaguchi and Nishina for a GaSe thin slab with the surface projected total phonon density calculated by a linear-chain model fitted to recent inelastic atom scattering data of GaSe (001). We conclude that in case of relevant differences between bulk and surface-perturbed phonon densities only ...

Inelastic Electron Tunneling Spectroscopy Study of Thin Gate Dielectrics

Advanced Materials, 2010
AbstractA broad range of materials is currently being studied for possible use as the insulating layer in next generation metal‐oxide‐semiconductor transistors. Inelastic electron tunneling spectroscopy (IETS) has become a powerful tool to characterize both the structural and electrical properties of the resulting device structures made from these ...

Inelastic electron tunneling spectroscopy on ultrahigh vacuum prepared tunnel junctions

Zeitschrift f�r Physik B Condensed Matter, 1983
Inelastic electron tunneling (IET) spectra of clean ultrahigh vacuum (UHV) prepared (Al/Al oxide/Pb) tunnel junctions are discussed. Microcrystalline Al oxide is shown to grow on these Al films. This is in contrast to the formation of amorphous Al oxide in the common high vacuum (HV) preparation process. The IET-spectra of UHV prepared tunnel junctions

Inelastic Electron Tunneling Spectroscopy in MIS and MS Tunnel Junctions

Journal of the Physical Society of Japan, 1981
Calculation of the tunneling conductance for inelastic tunneling process with excitation energy \( \hbar \omega \) are carried out, and it is clarified that inelastic electron tunneling spectroscopy (IETS) can be a useful tool for investigation of electronic states in semiconductors.

Inelastic tunneling spectroscopy and single-electron tunneling in an adjustable microscopic tunnel junction

Physical Review Letters, 1990
A remarkably stable microscopic tunnel junction can be made with two crossed wires separated by a monolayer of adsorbed molecules. Inelastic tunneling peaks of hydrocarbons are clearly resolved. A wide Coulomb blockade of single-electron tunneling is observed, indicating that stray capacitance does not influence the microscopic junction.
