Jagodzinski notation

TABLE 1 Seven of the most simple SiC polytypes with four notations (R = Ramsdell notation, J = Jagodzinski notation, Z = Zhadanov notation). They are listed by increasing percent hexagonality.

Another common notation for describing stacking of close-packed 36 nets (T nets) is that devised by Zhdanov (1945) (a number notation equivalent to Jagodzinski s notation). A short description of the Zhdanov symbol is the following a + is assigned if the order between a layer and its previous partner follows the... 

A few important examples of groups of homeotect structure types will be described in the following sections. A short list follows, in which the Jagodzinski-Wyckoff notation of the stacking pattern has been inserted according to the previously given indications.
