Analysis of polytype stability in PVT grown silicon …

2014/9/4· Because the structure of each single Si–C bilayer of A, B, or C stacks is the same for both 4H-SiC and 6H-SiC, to build a lattice model realizing the competitive growth of 4H and 6H polytypes in SiC, we assumed that the site positions in the first Si–C bilayer (A1) was the same for both 4H-SiC and 6H-SiC, with each site position in A1 having two polytype-tagged 4H and 6H, as shown in Fig. 1.

Lattice loion determines trace nitrogen dopants in SiC …

SiC is a compound, and thus has a complex crystal structure, which means that doping SiC is far more difficult than doping silicon . Since dopants should be light elements such as boron, nitrogen, aluminium, or phosphorus, there was no measurement method to study at which site in the SiC crystal they are loed, namely the silicon site or the carbon site.

Carbide — Wikipedia Republished // WIKI 2

The carbides of silicon and boron are described as "covalent carbides", although virtually all compounds of carbon exhibit some covalent character. Silicon carbide has two similar crystalline forms, which are both related to the diamond structure. Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms.
