INELASTIC ELECTRON TUNNELLING SPECTROSCOPY (lETS) OF SILANE COUPLING AGENTS
Inelastic Electron Tunnelling Spectroscopy (lETS) has been used to study monolayers of silane coupling agents adsorbed on aluminium oxide. The technique of lETS is surface specific and uses electrons to excite vibrational modes of the adsorbate. Since the tunnelling electrons perturb both the …

Electron Tunnelling Study of High-Temperature Superconductors
… Cambridge. The aim of this work was to use electron tunnelling spectroscopy to measure the density of excitation states of the recently discovered high-temperature superconductors. Tunnelling is the most sensitive method for measuring a superconductor’s energy gap, and historically has …

THE DURABILITY OF PHENOLIC ADHESIVES
… locus of failure in the joints, the technique of Electron Spectroscopy for Chemical Analysis (ESCA) was employed. Examination by ESCA revealed that, in many instances, the mode of failure was complicated and also. In some cases, contrary to the visual evidence. To complete the surface study, the …
