A polytype is described by the nuer of layers in the unit cell and a letter denoting the Bravais lattice type (C‐cubic, H‐hexagonal, R‐rhoohedral) (Ref. 9).The cubic polytype (3C) is referred to as β‐SiC, while all others are collectively referred to as a‐SiC (Ref. 10).
2002/11/30· Silicon with a pentavalent dopant is called N-type silicon. On the other hand, we may use a dopant that has only three valence electrons, such as B, Ga or Al. This causes a lack of one electron in one of the covalent bonds made by the dopant.

Abstract Silicon carbide (SiC) is the only known naturally stable group-IV semiconducting compound crystallizing in a large nuer of polytypes . The various types of SiC differ one from another only by the order in which successive planes of Si (or C) atoms are
The refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal character of the polytype. This relationship is not sufficiently
