This work illustrates the advantages of using p-polarized radiation at an incidence angle of 70° in contrast to the conventional unpolarized beam at normal (or near-normal) incidence for the infrared spectroscopic study of polycarbosilane, polysilaz

The effects of ion irradiation on the composition, structure, compactness, and surface hardness of polyorganosiloxane films synthesized by plasma-enhanced chemical vapor deposition were investigated as a function of the ion mass and fluence. The film

The present work describes the effects of diluting hexamethyldisilazane (HMDSN) vapor either in pure argon or in oxygen−argon mixtures on the solid film deposited from the resulting plasma. Such a dilution provides a manner of incorporating control

The effect of the incorporation of oxygen and nitrogen on the structure of films obtained by PECVD of hexamethyldisiloxane (HMDSO)-He-N 2 and HMDSO-He-O 2 mixtures is investigated using infrared and Raman spectroscopies. From transmittance spectra of

Amorphous films (a-C:H:Si and a-C:H:Si:O) were grown in a vacuum chamber containing a hot filament on substrates held on a copper plate to which a bias voltage could be applied. This modified hot-filament chemical vapor deposition process was used to
