Four silicon carbide mixture targets (mixture targets) with carbon contents of 50 mol%, 55 mol%, 60 mol% and 67 mol% were used to evaluate the characteristics of sputtered silicon carbide films as functions of the carbon content of the target. Furthermore, the stoichiometric SiC target (compound target) was
2020-8-17 · Moissanite (/ ˈ m ɔɪ s ən aɪ t /) is naturally occurring silicon carbide and its various crystalline polymorphs.It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial appliions due to its hardness, optical properties and thermal conductivity.
Its disadvantages include above all the price: whilst two-inch silicon wafers cost only a few dollars, the value of similar silicon carbide wafers runs into thousands. Low quality silicon carbide crystals are a popular abrasive material, also used in bulletproof vests and in the brake discs of the world''s most expensive cars, such as
The functionalized PCS nanospheres were either pyrolyzed as synthesized or coated on a silicon wafer at 1073 K under an argon atmosphere (RT–573 K at 150 K·h −1, then 5 h at 573 K, followed by heating to 973 K at 30 K·h −1. After reaching 973 K, the sample was heated to 1073 K at 120 K·h −1 and maintained for 2 h).

Dating of interstellar dust directly with astronomical methods is not possible. Neither is dating based on the decay of long-lived radioactive nuclides, due to current analytical limitations and unknown initial isotopic compositions. Here we present interstellar ages of individual presolar SiC grains from a meteorite. The ages are based on Ne isotopes produced by galactic cosmic rays.

Experimental data on diffusion of erbium and vanadium in porous and nonporous silicon carbide at 1700 and 2200°C have been used for modelling diffusion in porous SiC. It is shown that the consideration of pore structure modifiion under annealing via vacancy redistribution allows for satisfactory description of dopant diffusion. As expected, important contribution to the diffusion in the

2019-3-20 · Silicon carbide (SiC) has recently emerged as a promising material for the integration of defect qubit states into microfabried and nanofabried devices. The three most prevalent crystalline forms of SiC-termed 4H, 6H, and 3C-have all demonstrated deep-level defect states (color centers) with spin and optical properties similar to the negatively charged nitrogen vacancy center in diamond
ST’s silicon-carbide diodes take advantage of SiC’s superior physical characteristics over Si, with 4 times better dynamic characteristics and 15% less forward voltage, VF. Their low reverse recovery characteristics make ST’s silicon-carbide diodes a key contributor to energy savings in SMPS appliions and in emerging domains such as solar energy conversion, EV or HEV charging stations
