Bias-referenced X-ray photoelectron spectroscopy results are presented for cleaned and epoxy-treated sapphire and etched A6061 aluminum surfaces. No chemical shifts in the spectra were observed for sapphire or water-soaked or chromic-sulfuric-acid-et

Rapid solidification of iron oxides with silica was investigated as a method of making fine dispersions of magnetic phases within a non-magnetic matrix. Such a process applied to amorphous thin films may ultimately lead to solid-state dispersions of

Devitrification of amorphous melt-spun ribbons with compositions of Co66Cr14B20 and Fe43Cr25Ni20B12 was investigated as a method of making fine dispersions of magnetic phases within a non-magnetic matrix. Such a process may ultimately be applied to a

We have used radio frequency sputtering from Ni and NiO targets to produce thin films of about 300 A thickness [1 3] . The atomic arrangements in these films were sensitive to the deposition and the substrate temperatures, and the incorporation of ox

An XPS technique which uses a biased gold dot as a reference marker was used to measure the A12p, the 01s, and the Y 3d bond energies in single crystals of sapphire and in Ce-doped and Ca-doped crystals of yttrium aluminum garnet. The observed A12p a

A bias-reference XPS technique has been used to relate the apparent chemical shifts of the Ols oxide lines in a series of silica, alumina, magnesia, and phosphate powders to variations in the Fermi levels of these materials. The Fermi energies, E F ,

Specimens of 6061 and 5052 aluminum alloys which had been anodized and etched by several commonly used procedures were examined by means of bias-reference X-ray photoelectron spectroscopy (XPS). The spectra were compared with those obtained from sing

A prominent increase of the integrated intensity of the O ls energy level after exposure of fcc nickel films — but not hcp and amorphous nickel films — to oxygen is clearly observed by means of ESCA. It seems that in hcp and amorphous films, a co
