Silicon Carbide - Structure, Properties, and Uses of SiC
Silicon carbide is a very popular abrasive in modern lapidary owing to its durability and the relatively low cost of the material. It is, therefore, crucial to the art industry. In the manufacturing industry, this compound is used for its hardness in several abrasive machining processes such as honing, grinding, water-jet cutting, and sandblasting.

electric constants versus lattice constant for the (Al, Ga, In, N) system is shown in Fig. 6. The tensile strain caused by the growth of AlxGa1-xN on GaN results in a piezoelectric polarization, Ppz, that adds to the net spontaneous polarization, Psp, in a manner 3
Technology - epitaxial graphene on silicon carbide | …
The resulting lattice constant is commensurate to that of graphene and therefore it is said that graphene grows epitaxially. This has been confirmed only for graphene grown on the Si face of SiC. The reconstructed layer is called “buffer layer” or “zero layer”.
Low Pressure Chemical Vapor Deposition of Semiconducting Boron Carbide Thin Films on Silicon
Angstroms , while the lattice constant of the (100) plane in silicon is around 5.43 Angstroms. This yields a lattice mismatch of about 3.5%, which is within the commonly acceptable range. Thus, the (100) plane of silicon is chosen as the growth substrate for boron carbide deposition.
