Amorphous hydrogenated boron-carbon (a-B 1 x C x:H) thin films were prepared by radio-frequency plasma deposition using CH 4 and B 2 H 6 diluted in H 2 as precursor gases. The composition and density were determined by ion-beam analysis. The densities of the a-B:H and a-C:H films are similar with ϱ ≡ g cm 3.

Mechanical and Tribological Properties of Plasma Deposited a-C:H:Si:O Films have already been obtained in a previous study (Ul et al., ) by varying the proportion of oxygen from 0 to 80%.

The lower density of the film prepared with the highest oxygen proportion in the present work is attributed to the acceleration in the deposition rate as. We applied temperature-programmed desorption (TPD) spectroscopy to study the bonding of hydrogen in amorphous hydrogenated carbon (a–C:H) films.

Typical hard plasma-deposited a–C:H films with an initial hydrogen content (H/(H+C)) of about 30% were used as samples. About 85% of the initial hydrogen content is released in the form of H2, the rest in the form of sunplena.com: Wolfgang Jacob, Thomas Dürbeck, Thomas Schwarz-Selinger, Udo von Toussaint.

Feb 15,  · Fluorinated amorphous carbon films are proposed as low dielectric constant interlayer dielectrics for ULSI circuits. The films are deposited by plasma enhanced chemical vapor deposition with CH 4, CF 4 and C 2 F 6 in a parallel-plate rf ( MHz) reactor and a helicon wave reactor.

In a parallel-plate reactor, the dielectric constant of the amorphous carbon films deposited with CH 4 Cited by: In recent years, plasma deposited amorphous hydrogenated carbon (a-C:H) films have been widely used in scientific and industrial fields due to their excellent mechanical, chemical, tribological, optical, and electronic [1,2,3,4,5] sunplena.com by: 4.

Franceschini, DF, Freire, FL and Silva, SRP () Influence of precursor gases on the structure of plasma deposited amorphous hydrogenated carbon-nitrogen films APPLIED PHYSICS LETTERS, 68 (19). Amorphous silicon was present in both low- and high-frequency plasma-deposited silicon nitride films.

However, more amorphous silicon occurred in the films deposited at MHz than in those deposited at 30 kHz. Temperature significantly influenced adhesion, friction, and wear of the silicon nitride films. DLC films, thanks to their excellent hardness and wear resistance, are widely studied as protective coatings of components of fuel injectors and fuel pumps [1] [2].

The sp 2 to sp 3 carbon ratio and the hydrogen content define the type of DLC coating and, consequently, its properties [2]. Diamond-like carbon films deposited by hydrocarbon plasma sources Fig. Example of a partial XPS spectra with two different fitting methods of the C 1s peak, adapted from [18].
