β¦ Synopsis
Silicon with thermally-grown oxide overlayers m the thickness range IS-89 A IS studied by angulardcpendent XPS.
Electron attenuation lengths at 1382 eV are found to be 37 +-4 A in SiOz and 27 +-6 A in Si. Single-crystal effects and thin-layer anomalies are also discussed.

Overlayers of SiO 2 (nominally 4, 6 and 8 nm thick) on silicon, prepared by thermal oxidation, were investigated using x-ray photoelectron spectroscopy (XPS). The thickness of these overlayers was obtained from a measurement of the photoelectron intensities originating from the substrate and the oxi

Wettability has a dominant effect in oil recovery by waterflooding and in many other processes of industrial and environmental interest. Recently, the suggestion has been made that surface science analytical techniques (SSAT) could be used to rapidly determine the wettability of reservoir materials.
Polyimides have been extensively studied in view of their wide industrial applications. Adhesion to a substrate is essential for normal operation of devices. This problem is often solved by the use of an adhesion promoter on the surface of interest. A surface-sensitive technique such as XPS has prov
