From Pure Carbon to Silicon−Carbon Nanotubes: An Ab …

Ab initio methods are used for investigating structural and electronic properties of silicon−carbon nanotubes (SiCNTs). Tubes with different Si to C ratios were tested and the trend from C-rich to Si-rich SiCNTs is examined. Our results show that SiCNTs lose stability

Surface-state origin for the blueshifted emission in …

Higher etching current densities produce porous silicon carbide (PSiC) with CL emission wavelengths deeper in the ultraviolet. Photoluminescence (PL) is also blueshifted in anodically etched PSiC, although not to the extent of the CL emission, suggesting that different emissive states are accessed in CL and PL.

Measuring Silicon Carbide Particle Size - HORIBA

Measuring Silicon Carbide Particle Size Due to its high hardness, silicon carbide is used in many abrasive appliions either as a slurry or fixed in a matrix such as grinding wheels. It is also highly abrasion-resistant, so can be used in parts such as nozzles, seals, and bearing components.
