Home Optics Optical Materials: Silicon carbide mirrors benefit high-speed laser scanning Light weight, high stiffness, and good thermal conductivity make silicon carbide an ideal substrate for galvanometer mirrors in high-speed laser scanning systems.
Recently at NASA, thermally-stable pseudoamphoteric ohmic contacts to both n- and p-type silicon carbide have been developed. These composite contacts are not yet fully characterized or understood, and they could be further engineered to create even more robust, longer lasting silicon carbide devices with great reduction in processing time and costs.

Silicon carbide ceramics are egorized under advanced ceramics, which have properties similar to diamond. Usage of these ceramics is favorable in machine manufacturing, electronic & electrical, and automotive industries due to corrosion-resistant ceramic
Wide bandgap (WBG) semiconductors, such as silicon carbide (SiC), have emerged as very promising materials for future electronic components due to the tremendous advantages they offer in terms of power capability, extreme temperature tolerance, and high frequency operation.
The ultimate goal of this proposal is to provide NASA space SEE and TID tolerant high voltage and low on-resistance silicon carbide power devices that meet the capability performance goals in the NASA technology roadmap. These objectives are important for the
Amorphous silicon carbide nanosprings, as well as biphase (crystalline core/amorphous sheath) helical nanowires, have been synthesized by plasma enhanced chemical vapor deposition. Both variants grow via the vapor−liquid−solid mechanism. The formation of the amorphous silicon carbide nanosprings is explained in terms of the contact angle anisotropy model initially proposed to explain the

The inferred crystallographic class of circumstellar silicon carbide based on astronomical infrared spectra is controversial. We have directly determined the polytype distribution of circumstellar SiC from transmission electron microscopy of presolar silicon carbide from the Murchison carbonaceous meteorite. Only two polytypes (of a possible several hundred) were observed: cubic 3C and
