Silicon forms other useful compounds. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Sodium silie (Na 2 SiO 3), also known as water glass, is used in the production of soaps, adhesives and as an egg preservative. Silicon 4
Solid-state quantum emitters with spin registers are promising platforms for quantum communiion, yet few emit in the narrow telecom band necessary for low-loss fiber networks. Here, we create and isolate near-surface single vanadium dopants in silicon carbide (SiC) with stable and narrow emission in the O band, with brightness allowing cavity-free detection in a wafer-scale material. In

The complete sets of elastic constants of 4H and 6H silicon carbide single crystals were determined by Brillouin stering. The elastic constants of 6H SiC are C11=501±4, C33=553±4, C44=163±4, C12=111±5, and C13=52±9 GPa; the corresponding ones of 4H SiC are the same within experimental uncertainties. The compressibility, 4.5×10−3 GPa, is about 3–5 times smaller than those reported
