Chemically vapor deposited silicon carbide (SiC) for …
20/5/1990· Silicon carbide is widely considered to be the material of choice for mirror optics in vacuum ultraviolet (VUV) and X-ray appliions. For example, mirrors for de- flecting synchrotron radiation in large electron-storage rings must withstand high X-ray flux without degrada- tion or excessive thermal distortion, which affects trans- mission and energy resolution.

Silicon in 2016
Annual domestic production of total silicon materials (contained silicon) increased in 2017 (415,000 t) compared with 2016 production (384,000 t). There have been fluctuations, but overall domestic apparent consumption has mirrored production trends, exports have remained about the same, and imports of silicon materials have increased significantly over the last 50 years (fig. 1).
Bringing silicon carbide to the masses - News
When 3C-SiC is grown on a silicon (111) substrate, this produces the ideal template for hexagonal GaN, due to a lattice mismatch of approximately 3.5 percent at the SiC-silicon interface. Reducing mismatch between GaN and silicon is valued highly, because it holds the key to reducing the intrinsic defects found in GaN when this material is grown on highly mismatch substrates, such as silicon
