Silicon Carbide (SiC) Mirrors - Zygo Corporation
Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.

Titanium impurities in silicon, diamond, and silicon carbide
Here, we have carried a theoretical investigation on the electronic and the atomic structure, the spin state, and the stability of Ti impurities in silicon carbide, silicon, and diamond. We computed the Ti-related acceptor transition energies in all those materials, and using the model by Langer and Heinrich , we determined the valence band offset among Si, SiC, and diamond.
Bosch poised for leap in e-mobility technology - Bosch …
Silicon carbide semiconductors will transform e-mobility.” Harald Kroeger, meer of the Bosch board of management The reason is that the new technology also offers further potential savings down the line: the much lower heat losses of the chips, coined with their ability to work at much higher operating temperatures, mean that manufacturers can cut back on the expensive cooling of the
Chemistry paves the way for improved electronic …
The researchers discovered that it is possible to achieve epitaxial growth of indium nitride if silicon carbide is used as substrate, something that was not previously known. Furthermore, the indium nitride produced in this way is extremely pure, and among the highest quality indium nitride in the world.
Silicone - Wikipedia
Silicon is a chemical element, a hard dark-grey semiconducting metalloid, which in its crystalline form is used to make integrated circuits ("electronic chips") and solar cells. Silicones are compounds that contain silicon, carbon, hydrogen, oxygen, and perhaps other kinds of atoms as well, and have very different physical and chemical properties.
