摘要:

Aluminum is a very important element because of its many practical applications, and XPS provides an attractive method for the investigation of, and distinguishing between, aluminum and its compounds. The Al2pcore XPS spectra shows a substantial shift (about 2 eV) between the metal peak and compound peaks, and the metal peak width is much less than the width of the compound peaks. This fact has been used in numerous studies where the Al2pspectrum can be easily curve fitted to identify a percentage area due to the metal and due to aluminum compounds. Several measurements of this kind, representing aluminum metal and 11 of its compounds, have been collected in a special issue ofSurface Science Spectra. This Introduction summarizes the data to be presented and provides an overview of the use of and interpretation of XPS studies of aluminum and its compounds.

摘要:

The XPS spectra of argon ion etched aluminum metal were collected with a VSW HA150. This spectrometer is equipped with monochromatic AlKαx-radiation, a 16 channel multichannel detector, and an electrostatic hemispherical analyzer with a radius of 150 mm providing an instrument with exceptional capabilities. We report the Al 2pcore level with resolved 2p1/2and 2p3/2spin-orbit split components. The peak to valley separation on the high binding energy side between the spin orbit components was determined to be 0.18 eV and the separation between these components was 0.44 eV. The valence band, survey, and the Al 2s, O 1s, and C 1score levels are also reported.

摘要:

The XPS spectra of corrundum were collected with a VSW HA150 using monochromatic AlKαx-radiation. Monochromatic radiation provides a distinct clarity to the peak structure in the valence band of corrundrum due to the absence of interfering x-ray satellites from the intense O2sregion. Variations in the intensities and peak separation of the two-peak structure in the valence bands of the oxides, hydroxides, and oxyhydroxides of aluminum allow one to distinguish between these compounds. The valence band, survey, and the Al2s, Al2p, O1s, and C1score levels are reported.
