14/7/2016· Recently, a well-ordered siliene/silicon-carbide hybrid thin-film supported on Ru was reported. In our work, we modeled this system using density functional theory. The new thin-film consist of a monolayer of corner sharing [SiO 4]-tetrahedra on top of a [Si 2 C 3] monolayer supported on the Ru surface, as shown in figure 2 (b).). The siliene/silicon-carbide film differs from bilayer

Silicon carbide particles produced by laser pyrolysis are crystalline (in the cubic SiC structure) whereas oxide nanoparticles produced by laser ablation have a strongly disordered lattice. For the spectroscopic measurement, the particles are extracted from the condensation zone by a molecular beam technique and are deposited on a KBr substrate.

7/1/2015· The results of measurements of shock compression wave profiles for three modifiions of carbide ceramics in the stress range 3–19 GPa are presented. The dynamic elasticity and spall strength limits of the materials are determined. It is shown that these characteristics are sensitive to specific characteristics of reaction-sintered ceramics related to technological parameters of the process

Silicon carbide (SiC) has been recognized as a promising semiconductor material for high-temperature and high-power electronics because of its wide band gap and high breakdown field. SiC has many polytypes (e.g., 3C, 6H, 4H, and 15R), which display little difference in total energy, making them difficult to control in films.

Here, the term silicon-oxycarbide refers specifically to a carbon-containing silie glass wherein oxygen and carbon atoms share bonds with silicon in the amorphous, network structure. Thus, there is a distinction between black glass, which contains only a second-phase dispersion of elemental carbon, and oxycarbide glasses which usually contain both network carbon and elemental carbon.
