In this work we perform the results of study of thin amorphous carbon films (a-C) synthesized by magnetron sputtering of graphite target at direct current in argon atmosphere. Analyzing experimental data, we revealed the dependence between a-C films structure and substrate temperature. Local structure was studied by Raman spectroscopy. The position of G peak varied from 1545 cm−1 to 1570 cm−1. To...
The carbon films, of which the morphology change from the carbon nanotubes to the globe-like diamond microcrystalline aggregates during the deposition, have been grown for different growing times by microwave plasma chemical vapor deposition on a ceramic substrate with a Ti buffer layer. The compositions and structures of the carbon films were evaluated by Raman scattering spectroscopy, X-ray diffraction,...
Phase transformations occurring in materials under high pressures are important for a wide range of problems in materials science and solid-state physics. Most of the results in this area have been obtained using various sophisticated high-pressure cells. We studied solid-state phase transformations and amorphisation under high non-hydrostatic pressures in very simple experiments using a combination...
